NAME

       tin, rtin - A Usenet newsreader

SYNOPSIS

       tin  [[-h|-H|-V] |  [[[-a]  [-dlnq|-Q]  [-ArzxX]]  [[-R|-S]  -s News_dir] [-cuvZ] [-4|-6] [-N|-M address]
       [-o|-w]] [-D debug_level] [-G article_limit] [-f newsrc_file] [-g server] [-m  Mail_dir]  [-p  port]  [-I
       index_dir] [newsgroup[,...]]]

DESCRIPTION

       tin  is  a full-screen easy to use Usenet newsreader. It can read news locally (e.g., /var/spool/news) or
       remotely (rtin or tin  -r  option)  via  a  NNTP  (Network  News  Transport  Protocol)  server.  It  will
       automatically  utilize NOV newsoverview(5) style index files if available locally or via the NNTP [X]OVER
       command (RFC2980, RFC3977).

       tin has four separate levels of operation: Selection level, Group level, Thread level and Article  level.
       Use the Help ('h') command to view a list of the commands available at a particular level.

       On startup tin will show a list of the newsgroups found in ${TIN_HOMEDIR:-"$HOME"}/.newsrc. An arrow '->'
       or highlighted bar will point to the first newsgroup. Move to a group by using the  terminal  arrow  keys
       (terminal  dependent)  or  Down  ('j')  and Up ('k'). Use PgUp/PgDn (terminal dependent) or PageUp ('^U')
       (CTRL-U) and PageDown ('^D') (CTRL-D) to page up/down. Enter a newsgroup by pressing '<CR>'.

       The GroupNextUnreadArtOrGrp ('<TAB>') key enters the next newsgroup with unread articles.

OPTIONS

       -4          Force connecting via IPv4 to the remote NNTP server.

       -6          Force connecting via IPv6 to the remote NNTP server.

       -a          Toggle ANSI color (default is off).

       -A          Force authentication on initial connect.

       -c          Create/update  index  files  for  every  group  in  ${TIN_HOMEDIR:-"$HOME"}/.newsrc  or  file
                   specified by the ''-f'' option and mark all articles as read.

       -d          Don't load newsgroup descriptions and servers message of the day (interactive mode).

       -D debug-level
                   Enter  debug-level  (1  =  NNTP,  2  =  filter,  4 = newsrc, 8 = threading, 16 = memory, 32 =
                   attributes, 64 = misc).

       -f file     Use    the    specified    file    of    subscribed    to    newsgroups    in    place     of
                   ${TIN_HOMEDIR:-"$HOME"}/.newsrc.

       -g server   Use the server and newsrc specified in ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable.

       -G article-limit
                   Limit the number of articles/group to retrieve from the server.

       -h          Help listing all command-line options.

       -H          Brief introduction to tin that is also shown the first time it is started.

       -I dir      Directory     in     which     to     store     newsgroup    index    files.    Default    is
                   ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news.  This option has no effect if tin
                   retrieves its index files via NNTP and cache_overview_files is turned off.

       -l          Get         number         of         articles        per        group        from        the
                   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file. If reading via NNTP this is  done
                   with  the  LIST  command  (RFC3977  ).  This  might result in incorrect article counts but is
                   usually     faster     than     the     default      which      is      to      read      the
                   ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file (either directly or via LIST) and
                   then check the article count via NNTP GROUP command (RFC3977 ) ''-ln''. If reading  via  NNTP
                   and  LIST  COUNTS  (RFC6048  )  is  available  that is used instead as it gives more accurate
                   article counts.

       -m dir      Mailbox directory to use. Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.

       -M user     Mail unread articles to specified user for later reading. For more information  read  section
                   "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -n          Only load groups from the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file that are
                   subscribed to in the user's ${TIN_HOMEDIR:-"$HOME"}/.newsrc. This allows a noticeable speedup
                   when  connecting  via a slow line, but tin may not be able detect which groups are moderated.
                   See also ''-l''.

       -N          Mail unread articles to yourself  for  later  reading.  For  more  information  read  section
                   "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -o          Quick  post  all postponed articles and exit. In order for this to be really quick, it should
                   be used with ''-n'' if possible.

       -p port     Port to use if reading via NNTP  (default  is  119).  This  also  overrides  the  environment
                   variable $NNTPPORT if set.

       -q          Don't check for new newsgroups and skip loading the servers message of the day.

       -Q          Quick start. Start tin as quickly as possible. Currently this is equivalent to ''-nqd''.

       -r          Read  news  remotely  from  the  default  NNTP  server  specified in the environment variable
                   $NNTPSERVER or contained in the file /etc/news/server.

       -R          Read news saved by the ''-S'' option.

       -s dir      Save/read articles to/in directory. Default is ${TIN_HOMEDIR:-"$HOME"}/News.

       -S          Save unread articles for later reading by  the  ''-R''  option.  For  more  information  read
                   section "AUTOMATIC MAILING AND SAVING NEW NEWS".

       -u          Create/update  index  files  for  every  group  in  ${TIN_HOMEDIR:-"$HOME"}/.newsrc  or  file
                   specified by the ''-f'' option. This option is disabled if tin retrieves its index files  via
                   a NNTP server and cache_overview_files is turned off.

       -v          Verbose mode for ''-c'', ''-M'', ''-N'', ''-S'', ''-u'' and ''-Z'' options.

       -V          Print version and date information.

       -w          Quick  mode to post an article and then exit. In order for this to be really quick, it should
                   be used with ''-n'' if possible.

       -x          No-posting mode. You cannot post articles if you use this option.

       -X          No overwrite mode. ${TIN_HOMEDIR:-"$HOME"}/.newsrc and files in  ${TIN_HOMEDIR:-"$HOME"}/.tin
                   will not be overwritten but may be created if they don't exist.

       -z          Only  start tin if there is any new/unread news. If there is news tin will position cursor at
                   first group with unread news. Useful for putting in login file.

       -Z          Check if there is any new/unread news and exit with appropriate status. If ''-v''  option  is
                   specified the number of unread articles in each group is printed. An exit code 0 indicates no
                   news, 1 that an error occurred and 2 that new/unread news exists. Useful for writing scripts.

       tin can also dynamically change its options by the OptionMenu ('M') command. Any changes are  written  to
       ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.  For  more  information  see  section  "GLOBAL OPTIONS MENU AND TINRC
       CONFIGURABLE VARIABLES" and tin(5).

       A list of groups can be specified after the other command-line options. This can be useful if you wish to
       yank in or subscribe to a hand-picked subset of the active newsgroups. See the section "NEWSGROUP LISTS &
       WILDCARDS" for the types of pattern that tin understands.

       If you specify a  single  group-name,  or  a  wildcard  that  matches  a  single  group,  then  you  will
       automatically enter that group. Otherwise the normal group selection screen will appear, but with all the
       matching groups present too, as though you had yanked just those groups in.

       With the ''-w'' flag a given group-name is used as default group to post to. If more than one group or  a
       wildcard is specified only the first group respectively the first group that matches is used.

       Once  you  use  SelectYankActive  ('y') to yank in all active groups, or SelectToggleReadDisplay ('r') to
       toggle  the  read/unread  status,  then  the  command-line   groups   will   be   gone.   You   can   use
       SelectSyncWithActive  ('Y')  to reread the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file and
       get them back.

       NB: With the ''-n'' flag, only unsubscribed groups in the ${TIN_HOMEDIR:-"$HOME"}/.newsrc  file  (or  the
       newsrc-file  given by the ''-f'' command-line switch or via ${TIN_HOMEDIR:-"$HOME"}/.tin/newsrctable) can
       be matched.

       Command-line options have higher priority than attributes and tinrc options.  Thus,  command-line  option
       takes precedence over configured values.

USAGE

   NEWS ADMINISTRATION
       Maintaining Netnews on large networks of machines can be a pretty time consuming job as I discovered when
       I was given the job of maintaining our news system and news users.

       A user starting tin for the first time can be automatically subscribed to a list of newsgroups  that  are
       deemed  appropriate  by the news administrator. The subscriptions file should be created in your news lib
       directory (i.e., ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions) and should have file permissions set  to  0644.
       If  you read news via NNTP, then your news server must support the LIST SUBSCRIPTIONS command. It is part
       of the NNTP List Extensions (RFC6048 ) and all modern servers should understand it.

   SCREEN FORMAT
       tin has four separate levels of operation: Selection level, Group level, Thread level and Article level.

       At the Selection level the title displays (the name of the  newsserver  and)  the  number  of  subscribed
       groups (containing new unread articles). The newsgroups are displayed in the middle of the screen usually
       with the number of unread articles displayed on the same line in front, but  it  can  be  customized  via
       select_format.

       ->M    1     2  comp.security.announce  Announcements from the CERT abou
         M    2     1  news.admin.announce     Announcements for news adminstra

         X    5   124  news.software.readers   Discussion of software used to r

       There may also be a character prefixing the line. An explanation follows:

       u         This  group is unsubscribed. To see only your subscribed groups use the SelectToggleReadDisplay
                 ('r') or SelectYankActive ('y') toggle keys.

       M         This is a moderated group.  Any  posts  you  make  will  have  to  be  approved  by  the  group
                 administrator before it will be made public. tin will ask for confirmation before you post to a
                 moderated group.

       N         This is a new newsgroup which has been created since you last used tin. New newsgroups are  not
                 subscribed  to  by  default  (However,  see  the  $AUTOSUBSCRIBE / $AUTOUNSUBSCRIBE environment
                 variables).  Subscribe to it in the normal way if you wish the group to continue to  appear  in
                 your Selection Menu. Simply ignore new newsgroups and they will be gone the next time you start
                 tin. You will have to yank in all the groups to find them in a later session.

       D         This group no longer exists. If you no longer wish to see this group then unsubscribe  from  it
                 in  the  normal  way.  This  flag  will only appear if you have set strip_bogus to "ask" in the
                 Options Menu.

       X         You may no longer make posts to this group.  Often  a  group  will  be  superseded  by  a  more
                 appropriately named one.

       =         This  group has been renamed and you may no longer post to it. If you do, then you will receive
                 an error from your newsserver telling you the correct group to post to.

       At the Group level the title contains the name of the group, the  number  of  conversation  threads,  the
       abbreviated  threading method (thread_articles), the limit of articles to get (if set; getart_limit), the
       total number of (unread) articles (art_marked_read or art_marked_unread),  the  number  of  hot  articles
       art_marked_selected,  the  number  of read hot articles (if any; art_marked_read_selected), the number of
       recent articles (art_marked_recent) and the number of killed articles (art_marked_killed). I.e.:

                   alt.sources (5B -50/23+ 0* 3o 0K)

       The  characters  after  the  numbers  are  depending  to  the  configuration   and   if   your   are   in
       show_only_unread_arts  mode  or not. Some numbers could be missing if the specific option is not enabled.
       It might also contain an 'M', 'X' or '=' (see above; doesn't work with the ''-n''  command-line  switch!)
       if the group is moderated, set to no posting or postings to it get redirected.

       If  a  thread  has  unread  articles  it is marked with art_marked_unread in front of the total number of
       articles in the thread. If there  are  recent  articles  within  the  thread  it  might  be  marked  with
       art_marked_recent  in  front  of  the  total number of articles in the thread - this is controlled by the
       recent_time option. If a thread has hot articles in it  (see  also  section  "FILTERING  ARTICLES")  it's
       marked  with  art_marked_selected  in  front of the total number of articles in the thread. The number of
       lines of the first (unread) article in the thread might also be shown right before the subject - this  is
       controlled by the show_info option. The display can be customized via group_format.

       The look of the Selection, Group and Thread level can be customized. See  the  section  "CUSTOMIZING  THE
       SCREEN FORMAT".

   COMMON MOVING KEYS
       This table shows the common keys used for moving around all levels within tin.

              Line Down             Down arrow   Down (j or ^N)

   COMMON EDITING COMMANDS
       An emacs style editing package allows the easy editing of input strings.  An history list allows the easy
       reuse of previously entered strings.  In  addition  to  the  cursor  keys,  the  following  commands  are
       available when editing a string:

       ^A, ^E    move to beginning or end of line, respectively.

       ^F, ^B    non-destructive move forward or back one location, respectively.

       ^D        delete the character currently under the cursor, or send EOF if no characters in the buffer.

       ^H, <DEL> delete character left of the cursor.

       ^K        delete from cursor to end of line.

       ^P, ^N    move through history, previous and next, respectively.

       ^L, ^R    redraw the current line.

       <CR>      places line on history list if non-blank, appends newline and returns to the caller.

       <ESC>     aborts the present editing operation.

   GLOBAL COMMANDS
       The following commands are available at all 4 menu levels and always have the same effect.

       ShellEscape '!'
                 Shell  escape.  ShellEscape  by  itself  will launch a shell, ShellEscape <command> will run an
                 external <command>. This facility may have been disabled by the System Administrator.

       ToggleColor '&'
                 Toggle use of ANSI color.

       RedrawScr '^L'
                 Redraw the current screen.

       ScrollUp '<'
                 Scroll screen up by one line.

       ScrollDown '>'
                 Scroll screen down by one line.

       Postponed 'O' '^O'
                 Reload postponed article. If your system blocks the Postponed key you must quote it by pressing
                 '^V'  (CTRL-V)  first. The postpone-menu offers the following actions: PromptYes ('y') = reload
                 and spawn editor; PostponeOverride ('Y') = post article (without spawning editor);  PostponeAll
                 ('A')  =  post  all  postponed  articles  (without spawning editor); PromptNo ('n') = skip this
                 article; Quit ('q') = quit postponed menu. Currently there is  no  'simple'  way  to  delete  a
                 postponed  article  from  the  postponed-file,  you  have to use the following command sequence
                 instead: reload it with Postponed, enter editor with PromptYes, quit  editor,  discard  posting
                 with Quit ('^O''y''q'). See also ''-o'' command-line switch.

       Help 'h'  Help  screen  of  commands  available  on  the  current  menu.  You  can use SearchSubjF ('/'),
                 SearchSubjB ('?') and SearchRepeat ('\') to search on this screen. Quit ('q')  returns  to  the
                 menu.

       ToggleHelpDisplay 'H'
                 Toggle the display of help mini menu at the bottom of the screen.

       DisplayPostHist 'W'
                 List  articles  posted  by user. The date posted, the newsgroup and the subject are listed. You
                 can use SearchSubjF ('/'), SearchSubjB ('?') and SearchRepeat ('\') to search on  this  screen.
                 Quit ('q') returns to the menu.

       Version 'v'
                 Print tin version information.

   NEWSGROUP SELECTION COMMANDS
       4         Select group 4.

       SelectResetNewsrc '^R'
                 Reset  ${TIN_HOMEDIR:-"$HOME"}/.newsrc  file.  This  will destroy all records of which articles
                 have been read, so use this carefully.

       SetRange '#'
                 Choose a range of articles to be affected by the next command. See  the  section  "RANGES"  for
                 more information.

       SelectSortActive '.'

   GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES
       At  startup,  tin  reads  in the configuration files (see also tin(5)).  They contain a list of variables
       that can be used to  configure  the  way  tin  works.  If  it  exists,  the  global  configuration  file,
       ${TIN_LIBDIR:-NEWSLIBDIR}/tinrc  is  read.  After  that,  the  user's own configuration file is read from
       ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc. The global file is useful for distributing  system-wide  defaults  to
       new users who have no private tinrc yet.

       The  variables are user configurable by editing ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc directly. Most of them
       can also be set in the GLOBAL OPTIONS MENU which is accessed by pressing OptionMenu ('M') at all  levels.
       It   allows   the   user  to  customize  the  behavior  of  tin.  The  options  are  saved  to  the  file
       ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc when you exit tin so don't  edit  the  file  directly  whilst  tin  is
       running.

       In  the  options  menu  use  the  cursor  keys in the usual way to move around. Use ConfigSelect ('^J' or
       '<CR>') to 'open' the option you wish to change. You will need to enter a new value or use  '<SPACE>'  to
       toggle  the  available  options.  ConfigSelect will save the new value, '<ESC>' will abort without saving
       changes.

       As with the other menus, RedrawScr ('^L')  will  redraw  the  screen.  You  can  use  SearchSubjF  ('/'),
       SearchSubjB  ('?')  and  SearchRepeat  ('\')  to search for a specific option. Use Quit ('q') to exit the
       option menu and keep your changes. Use QuitTin ('Q') to exit without keeping your changes.

       The options menu provides access to the attributes menu for the current group by  the  ConfigToggleAttrib
       ('<TAB>')  command.  Pressing  ConfigToggleAttrib  again  toggles  back  to  the  options  menu. For more
       information see section "ATTRIBUTES MENU AND GROUP ATTRIBUTES".

       The ConfigScopeMenu ('S') command brings up the scopes menu. For more  information  see  section  "SCOPES
       MENU".

       Here  is  a full list of all the available variables. The name in braces is the name of the corresponding
       setting in ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.

           Default is OFF.

       Invocation of your editor (editor_format)
           The  format  string  used to create the editor start command with parameters.  Default is "%E +%N %F"
           (i.e., /bin/vi +7 .article).

       Force redraw after certain commands (force_screen_redraw)
           Specifies whether a screen redraw should always be done after certain external commands.  Default  is
           OFF.

       Number of articles to get (getart_limit)
           If  getart_limit  is  >  0  not more than getart_limit articles/group are fetched from the server. If
           getart_limit is < 0 tin will start fetching articles from your first unread minus absolute  value  of
           getart_limit. Default is 0, which means no limit.

       Catchup group using left key (group_catchup_on_exit)
           If ON catchup group when leaving with the left arrow key. Default is ON.

       Format string for the Group level (group_format)
           Format  string  tin  uses  for  Group  level  representation. See the section "CUSTOMIZING THE SCREEN
           FORMAT". Default is "%n %m %R %L  %s  %F".

       Go to the next unread article with (goto_next_unread)
           Which keys tin should accept to jump to the next unread article.   Possible  is  any  combination  of
           PageDown  and  PageNextUnread.   When PageDown is set tin jumps to the next article at the end of the
           current one. When PageNextUnread is set tin jumps immediately to the next article when PageNextUnread
           ('<TAB>') is pressed. Default is PageNextUnread.

       Max. length of group names shown (groupname_max_length)
           Maximum  length  of the names of newsgroups to be displayed so that more of the newsgroup description
           can be displayed. Default is 32.

       Display uue data as an attachment (hide_uue)
           If set to 'No' then raw uuencoded data is displayed. If set to 'Yes' then sections of uuencoded  data
           will  be  shown  with  a  single  tag  line  showing  the  size and filename (much the same as a MIME
           attachment). If set to 'Hide all' then any line that looks like uuencoded data will be folded into  a
           tag line.  This is useful when uuencoded data is split across more than one article but can also lead
           to false positives. This setting can also be toggled in the article viewer. Default is 'No'.

       External inews (inews_prog)
           Path, name and options of external inews(1).  If you are  reading  via  NNTP  the  default  value  is
           --internal  (use  built-in NNTP inews), else it is "inews -h". The article is passed to inews_prog on
           STDIN via '< article'.

       (info_in_last_line)
           If ON, show current group description or article subject in the last  line  (not  in  the  pager  and
           global menu) - ToggleInfoLastLine ('i') toggles setting. This facility is useful as the full width of
           the screen is available to display long subjects. Default is OFF.

       Use interactive mail reader (interactive_mailer)
           Interactive mailreader: if greater than 0 your mailreader will be invoked earlier for  reply  so  you
           can  use  more  of its features (e.g. MIME, pgp, ...). 1 means include headers, 2 means don't include
           headers (old use_mailreader_i=ON option). 0 turns off usage. This option has to  suit  mailer_format.
           Default is 0.

       Use inverse video for page headers (inverse_okay)
           If ON use inverse video for page headers and URL highlighting.  Default is ON.

       Keep failed arts in ~/dead.articles (keep_dead_articles)
           If  ON  keep  all  failed  postings in ${TIN_HOMEDIR:-"$HOME"}/dead.articles besides keeping the last
           failed posting in ${TIN_HOMEDIR:-"$HOME"}/dead.article. Default is ON.

       Filter which articles (kill_level)
           This option controls the processing and display of articles that are killed.  There are 3 options:

            0  Kill only unread arts is the 'traditional' behavior of tin. Only unread articles are killed  once
               only by marking them read. As filtering only happens on unread articles with kill_level set to 0,
               art_marked_killed and art_marked_read_selected are only shown once. When you  reenter  the  group
               the mark will be gone.

            1  Kill  all  arts  &  show  with  K will process all articles in the group and therefore there is a
               processing overhead when using this option. Killed articles are threaded as normal but they  will
               be marked with art_marked_killed.

            2  Kill  all  arts  and  never  show will process all articles in the group and therefore there is a
               processing overhead when using this option. Killed articles simply does not get displayed at all.
       Default is 0 (Kill only unread arts).

       Use 8bit characters in mail headers (mail_8bit_header)
           Allows 8bit characters unencoded in the header of mail message. Default is  OFF.  Turning  it  ON  is
           effective  only  if mail_mime_encoding is also set to 8bit. Leaving it OFF is safe for most users and
           compliant to Internet Mail Standard (RFC5322  and RFC2047 ). Default is OFF.

       Mail address (mail_address)
           User's mail address (and full name), if not username@host.  This  is  used  when  creating  articles,
           sending mail and when pgp(1) signing.

       MIME encoding in mail messages (mail_mime_encoding)
           MIME  encoding  of  the  body  in  mail message, if necessary (8bit, base64, quoted-printable, 7bit).
           Default is quoted-printable.

       Quote line when mailing (mail_quote_format)
           Format  of  quote  line  when   replying   (via   mail)   to   an   article   (%A=Address,   %D=Date,
           %F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is
           "In article %M you wrote:"

       Format of the mailbox (mailbox_format)
           Select one of the following mailbox-formats: MBOXO (default, except on SCO), MBOXRD or MMDF  (default
           on  SCO).  See  mbox(5) and RFC4155 for more details on MBOXO and MBOXRD and mmdf(5) for more details
           about MMDF.

       Mail directory (maildir)
           The directory where articles/threads are to be saved in mbox(5) format. This feature  is  mainly  for
           use with the elm(1) mail program. It allows the user to save articles/threads/groups simply by giving
           '=' as the filename to save to.  Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.

       Invocation of your mail command (mailer_format)
           The format string used to create the mailer command with parameters that is used for mailing articles
           to  other  people. Default is '%M "%T" < %F' (e.g., /bin/mail "iain" < .article). The flexible format
           allows other mailers with different command-line parameters to be used such as 'elm -s  "%S"  "%T"  <
           "%F"'  (e.g.,  elm  -s "subject" "iain" < .article) or 'sendmail -oi -oem -t < %F' (e.g. sendmail -oi
           -oem -t < .article).

       'Mark as (un)read' ignores tags (mark_ignore_tags)
           When this is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead ('K'), MarkThdUnread  ('Z')  at  Group
           level  and  MarkArtUnread  ('z')  at  Thread level functions mark just the current article or thread,
           ignoring other tagged, (un)read articles. When OFF, the same function presents a menu with choices of
           the current thread or article, all tagged, unread articles, or nothing.

       Mark saved articles/threads as read (mark_saved_read)
           If ON mark articles that are saved as read. Default is ON.

       Viewer program for MIME articles (metamail_prog)
           Path,  name  and  options of external metamail(1) program used to view non-textual parts of articles.
           To use the built-in viewer, set to --internal. This is the default  value  when  metamail(1)  is  not
           installed. Leave it blank if you don't want any automatic viewing of non-textual attachments. The 'V'
           command can always be used to manually view any attachments.  See also ask_for_metamail.

       MM_CHARSET (mm_charset)
           Charset supported locally, which is also used for MIME header (charset parameter and charset name  in
           header  encoding)  in mail and news postings. If MIME_STRICT_CHARSET is defined at compile time, text
           in charset other than the value of this parameter is considered not displayable  and  represented  as
           '?'.  Otherwise, all character sets are regarded as compatible with the display. If it's not set, the
           value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default  is  used  in
           case  neither  of  them is defined. If your system supports iconv(3), this option is disabled and you
           should use mm_network_charset instead.

       MM_NETWORK_CHARSET (mm_network_charset)
           Charset  used  for   posting   and   MIME   headers;   replaces   mm_charset.    Conversion   between
           mm_network_charset  and  local  charset (determined via nl_langinfo(3)) is done via iconv(3), if this
           function is not available on your system this option is disabled  and  you  have  to  use  mm_charset
           instead. mm_network_charset is limited to one of the following charsets:
              US-ASCII,      ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16},      KOI8-{R,U,RU}      EUC-{CN,JP,KR,TW},
              ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
           Not all values might work on your system, see iconv_open(3) for more details. If it's  not  set,  the
           value  of  the  environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in
           case neither of them is defined.

       Attribute of highlighting with _dash_ (mono_markdash)
           Character attribute of words emphasized like _this_. It depends on your terminal which attributes are
           usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with /slash/ (mono_markslash)
           Character attribute of words emphasized like /this/. It depends on your terminal which attributes are
           usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with *stars* (mono_markstar)
           Character attribute of words emphasized like *this*. It depends on your terminal which attributes are
           usable. See also word_h_display_marks and word_highlight.

       Attribute of highlighting with -stroke- (mono_markstroke)
           Character attribute of words emphasized like -this-. It depends on your terminal which attributes are
           usable. See also word_h_display_marks and word_highlight.

       (newnews)
           These are internal timers used by tin to keep track of new newsgroups.  Do not change them unless you
           understand what they are for.

       Display these header fields (or *) (news_headers_to_display)
           Which news headers you wish to see. If you want to see _all_ the headers, place an '*' as this value.
           This is the only way a wildcard can be used.  If you enter 'X-'  as  the  value,  you  will  see  all
           headers  beginning  with  'X-' (like X-Alan or X-Pape). You can list more than one by delimiting with
           spaces. Not defining anything turns off this option.

       Do not display these header fields (news_headers_to_not_display)
           Same as news_headers_to_display except it denotes the opposite. An  example  of  using  both  options
           might  be  if  you  thought  X-  headers  were  A  Good  Thing(tm),  but  thought  Alan and Pape were
           miscreants...  well   then   you   would   do   something   like   this:   news_headers_to_display=X-
           news_headers_to_not_display=X-Alan X-Pape.  Not defining anything turns off this option.

       Quote line when following up (news_quote_format)
           Format  of quote line when posting/following up an article (%A=Address, %D=Date, %F=Fullname+Address,
           %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Initials). Default is "%F wrote:".

       NNTP read timeout in seconds (nntp_read_timeout_secs)
           Time in seconds to wait for a response from the server. Default is 120.  Setting this to 0  means  no
           timeout.

       Unicode normalization form (normalization_form)
           The normalization form tin should use to normalize unicode input.  The possible values are:

            0  None: no normalization

            1  NFKC: Compatibility Decomposition, followed by Canonical Composition

            2  NFKD: Compatibility Decomposition

            3  NFC: Canonical Decomposition, followed by Canonical Composition

            4  NFD: Canonical Decomposition
       Some  normalization  modes  are  only  available  if they are supported by the library tin uses to do the
       normalization. NFC should be used if possible.

       Use 8bit characters in news headers (post_8bit_header)
           Allows 8bit characters unencoded in the header of a news article,  if  set  this  also  disables  the
           generation  of  MIME-headers  when  they  are  usually  required.  Default  is  OFF.  Only enacted if
           post_mime_encoding is also set to 8bit. In a number of local hierarchies where  8bit  characters  are
           used, using unencoded (raw) 8bit characters in header is acceptable and sometimes even recommended so
           that you need to check the convention adopted in the local hierarchy of your  interest  to  determine
           what to do with this and post_mime_encoding.

       MIME encoding in news messages (post_mime_encoding)
           MIME  encoding  of  the  body  in news message, if necessary. (8bit, base64, quoted-printable, 7bit).
           Default is 8bit, which leads to no encoding. base64 and quoted-printable  are  usually  undesired  on
           usenet.

       View post-processed files (post_process_view)
           If  ON,  then  tin  will  start  an  appropriate  viewer  program to display any files that were post

           compressed when quoting multiple times (for example, '> > >' will be turned into '>>>'). The  default
           is to compress quotes, and to quote empty lines.
           When  you are viewing an article in raw mode ('^H'), and follow up or reply to it, the signature will
           be quoted even if it would otherwise not be.  If show_signatures is  off,  then  the  signature  will
           never be quoted.

           If  enabled  tin  uses  slrnface(1)  to interpret the ''X-Face:'' header. For this option to have any
           effect, tin must be running in an xterm(1x) and slrnface(1) must be in your $PATH. Default is OFF.

       Use UTF-8 graphics (utf8_graphics)

           Allows  you  to select how tin matches strings. The default is 0 and uses the wildmat notation, which
           is how this has traditionally been handled.  Setting this to 1 allows you to use  perl(1)  compatible
           regular  expressions  pcre(3)  (see  also  perlre(1)  and pcrepattern(3)).  You will probably want to
           update your filter file if you use this regularly.  NB: Newsgroup names will always be matched  using
           the wildmat notation.

       What to display instead of mark (word_h_display_marks)
           Should  the  leading  and ending stars, slashes, strokes and dashes also be displayed, even when they
           are highlighting marks?

            0  no

            1  yes, display mark

            2  print a space instead

       Word highlighting in message body (word_highlight)
           Enable word highlighting. See word_h_display_marks for the options available. If use_color is enabled
           the  colors  specified  in  col_markdash, col_markslash, col_markstar and col_markstroke are used for
           word  highlighting  else  the  character  attributes  specified  in  mono_markdash,   mono_markslash,
           mono_markstar and mono_markstroke are used. Default is ON.

       Page line wrap column (wrap_column)
           Sets the column at which a displayed article body should be wrapped.  If this value is equal to 0, it
           defaults to the current screen width.  If this value is greater than your current  screen  width  the
           part  off-screen  is  not displayed. Thus setting this option to a large value can be used to disable
           wrapping. If this value is negative the wrap margin is the current screen width plus the given  value
           (as  long  as the result is still positive, otherwise it will fall back to the current screen width).
           Default is 0, wrapping at the current screen width.

       Quote line when cross-posting (xpost_quote_format)
           Format is the same as for news_quote_format, this is used when answering to a crossposting to several
           groups with no ''Followup-To:'' set.

   ATTRIBUTES MENU AND GROUP ATTRIBUTES
       tin  allows  certain attributes to be set on a per group basis. If it exists, the global attributes file,
       ${TIN_LIBDIR:-NEWSLIBDIR}/attributes  is   read.   After   that,   the   user's   own   attributes   file
       ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes  is  read.  The global attributes file is useful for distributing
       system-wide defaults to new users who have no private attributes file yet.

       Note that the scope=<grouplist> line has to be specified before the attributes  are  specified  for  that
       list.  All  attributes are set to a reasonable default so you only have to specify the attribute that you
       want to change (e.g., savedir). All toggle attributes are set  by  specifying  ON/OFF.  Otherwise,  these
       function exactly the same as their global equivalents. For more details see tin(5).

       Attributes  can  also  be  changed  from  the attributes menu which can be accessed by ConfigToggleAttrib
       ('<TAB>') from the options menu or ScopeSelect ('^J' or '<CR>') from the  scopes  menu.   The  attributes
       menu  looks  and  behaves very similar to the options menu. The title shows the current scope. Attributes
       set in the current scope are marked with '+' to the left of the attributes number.

       Besides the keys for moving around and changing values known from the options menu  the  attributes  menu
       provides the following command: ConfigResetAttrib ('r') which resets an attribute to a default value.

   SCOPES MENU
       The  scopes menu (accessible from the options menu with ConfigScopeMenu ('S')) shows all scopes read from
       the global and local attributes file.  Scopes from the global attributes file are marked with '!' to  the
       left of the scope number. Delete/rename/move are not possible with those scopes.

       In  addition to the common moving keys the following commands are available: ScopeSelect ('^J' or '<CR>')
       enter the attributes menu for the current scope, ScopeEditAttributesFile ('E') edit the local  attributes
       file,  ScopeAdd  ('a')  add a new scope, ScopeDelete ('d') delete the current scope, ScopeMove ('m') move
       the current scope to a new position, ScopeRename ('r') rename the current scope. ToggleHelpDisplay  ('H')
       toggles the help mini menu at the bottom of the screen.

   FILTERING ARTICLES
       When  there  is  a  subject  or  an  author  which  you are either very interested in, or find completely
       uninteresting, you can easily instruct tin to auto-select or auto-kill articles that match rules that you
       specify. This can be anything from the name of the author to the number of lines in an article.

       When  tin  starts  up the user's kill-file ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (see also tin(5)) is read.
       Each time a newsgroup is entered the rules are applied and articles killed or  selected  when  they  meet
       certain criteria.

       The  degree to which rules are applied depend on the kill_level tinrc setting. By default killed articles
       will only be marked read. Adjust kill_level for more aggressive processing. Articles that match an  auto-
       selection rule are marked with a ''*''.

       Filtering  rules  can  be  manually  entered  into ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (but don't do this
       whilst running tin else you will lose your changes) or by using an on-screen menu within tin.

       The filtering capabilities of tin have been significantly enhanced  over  previous  versions  to  include
       scoring  and  better  pattern  matching.  It  is  recommended that you read the file filtering in the tin
       documentation directory. This file can also be read online at
       <http://www.tin.org/filtering.txt>.

       The on-screen filtering menu is accessed by pressing MenuFilterKill ('^K') or MenuFilterSelect ('^A')  at
       the  Group  and  Article levels. It allows the user to kill or select an article that matches the current
       ''Subject:'' line, ''From:'' line or a string entered by the user. The user entered string can be applied
       to  the  ''Subject:'' or ''From:'' line of an article. The filter can be limited to the current newsgroup
       or it can apply to all newsgroups. Once entered the user can abort the  command  and  not  save  the  new
       filter, edit the full filter file or save filter.

   POSTING ARTICLES
       tin  allows posting of articles, follow-up to already posted articles and replying direct through mail to
       the author of an article.

       Use the Post ('w') command to post an article to a  newsgroup.   After  entering  the  post  subject  the
       default  editor (i.e., vi(1)) or the editor specified by the $VISUAL or $EDITOR environment variable will
       be started and the article can be entered. To crosspost articles simply add a comma and the name  of  the
       newsgroup(s)  to  the  end  of the ''Newsgroups:'' line at the beginning of the article. After saving and
       exiting the editor you are asked if you wish to a)bort posting the article, e)dit the  article  again  or
       p)ost the article to the specified newsgroup(s).

       Use  the DisplayPostHist ('W') command to display a history of the articles you have posted. The date the
       article was posted, which newsgroups the article  was  posted  to  and  the  articles  subject  line  are
       displayed.

       Use  the PageFollowupQuote ('f'), PageFollowup ('F') or PageFollowupQuoteHeaders ('^W') command to post a
       follow-up article to an already posted article. The PageFollowupQuote command will copy the text  of  the
       original article into the editor. The PageFollowupQuoteHeaders command will copy the text and all headers
       of the original article into the editor. The editing procedure is the same as  when  posting  an  article
       with the Post ('w') command.

       Use  the  PageReplyQuote  ('r'),  PageReply ('R') or PageReplyQuoteHeaders ('^E') command to reply direct
       through mail to the author of an already posted article. The PageReplyQuote command will copy the text of
       the  original  article  into  the  editor.  The  PageReplyQuoteHeaders command will copy the text and all
       headers of the original article into the editor. The editing procedure is the same  as  when  posting  an
       article  with  the  Post  ('w') command. After saving and exiting the editor you are asked if you wish to
       abort sending the article via PostAbort ('a'), edit the article again via  PostEdit  ('e')  or  send  the
       article to the author via PostSend ('s').

   CUSTOMIZING THE ARTICLE QUOTE STRING
       When  posting  a followup to an article or replying direct to the author of an article via email the text
       of the article can be quoted. The beginning of the quoted text can contain information about  the  quoted
       article  (e.g.,  Name  and  the  Message-ID  of  the  article). To allow for different situations certain
       information from the article can be used in the quoted string. The following variables  are  expanded  if
       found in the tinrc variables mail_quote_format, news_quote_format or xpost_quote_format:
              %A  Address (Email)
              %D  Date (uses date_format)
              %F  Full address (%N <%A>)
              %G  Groupname
              %M  Message-ID
              %N  Fullname of author
              %C  Firstname of author
              %I  Initials of author
       e.g.,
              mail_quote_format=On %D in %G you wrote:
              news_quote_format=In %M, %F wrote:
       would expand to:

       The  quoted  text  section  of  an article is marked by a preceding quote string at the beginning of each
       quoted line. The default quote string is set to '>_'. The default can be changed  by  setting  the  tinrc
       variable quote_chars to ones own preference. (Note that '_' underline is used to represent a space).

   MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
       The  command  interface  to  GroupMail,  PageMail, PostMail or ThreadMail ('m'), Pipe ('|'), Print ('o'),
       PageRepost  or  GroupRepost  ('x')  and  GroupSave,  PageSave  or  ThreadSave  ('s'  and   GroupAutoSave,
       PageAutoSave or ThreadAutoSave 'S') articles is the same for ease of use.

       Auto-saving  with  *AutoSave  ('S')  is  a  special  case and operates only on marked articles. They will
       processed without any further prompting according to the default save parameters defined in tinrc  or  by
       any attributes set for the current group.

       Otherwise,  the  initial  prompt will ask you to select which article, thread, hot (auto-selected), regex
       pattern, tagged articles you wish to mail, pipe etc.

       Tagged articles must have already been tagged with a *Tag ('t')  command.  All  tagged  articles  can  be
       untagged by a *Untag ('U') untag command.

       If  a  regex  pattern  is  selected you are asked to enter a pattern (e.g., to match all articles subject
       lines containing 'net News' you enter "net News"). Any articles that match the entered expression will be
       mailed, piped etc. See also the wildcard tinrc variable for advanced pattern matching options.

       Various  expansion characters are recognized when entering the directory and file to save to. Environment
       variables (prefixed with '$') and  user  home  directories  (prefixed  by  '~'  or  '~username')  can  be
       specified.  Environment variables can themselves contain other special characters.

       To save articles to a mailbox enter '=<mailbox name>' when asked for the save filename. If you enter just
       '=' then articles will be saved to a mailbox with the name of the current  newsgroup  (eg,  alt.sources).
       See maildir.

       To  save  in  savedir/<news.group.name>/<filename> format enter '+<filename>'.  Environment variables are
       allowed within a filename (e.g., $SOURCES/dir/filename). See savedir.

       When saving articles you can specify whether the saved files should be post processed. A default  process
       type can be set via post_process_type.

   AUTOMATIC MAILING AND SAVING NEW NEWS
       tin  allows  new/unread news articles to be mailed (''-M'' and ''-N'' option) or saved (''-S'' option) in
       batch mode for later reading. Useful when going on holiday and you don't want to  return  and  find  that
       expire  has  removed  a whole load of unread articles. Best to run via cron(1) everyday while away, after
       which you will be mailed a report of which articles were mailed/saved from which newsgroups and the total
       number  of  articles  mailed/saved.  Articles  are saved in a private news structure under your <savedir>
       directory (default is ${TIN_HOMEDIR:-"$HOME"}/News). Be careful of using this option if you read a lot of
       groups because you could overflow your file system.

       When  using ''-S'' together with a given directory to save to (''-s'' option), the same directory must be
       specified when reading the articles by ''-R''.

       If you only want to save some of your groups use the batch_save tinrc variable. Set to ON or OFF in tinrc
       to  enable/disable  saving  of all groups and then use the batch_save attribute to fine tune which groups
       you want to have saved. For example, if you want to save most of your groups, then set batch_save  to  ON
       in tinrc and selectively turn off the ones you don't want using attributes.

       tin -M iain -c -f newsrc.mail
                           (mail  any  unread  articles in newsgroups specified in file newsrc.mail to the local
                           user iain and mark them as read)

       tin -S -c -f newsrc.save
                           (save any unread articles in newsgroups specified in file newsrc.save and  mark  them
                           as read)

       tin -R              (read any articles saved by tin -S)

   RANGES
       A range is simply a group of items marked using the SetRange ('#') key. Certain tin commands will operate
       on a range if one exists rather than just the current  item.  A  range  is  an  expression  of  the  form
       <min>-<max>,  e.g.  10-15  will  highlight items 10 through 15 on the current screen. Other than absolute
       numeric positions, '.' can be used in place of the current cursor position and '$' can be  used  to  mean
       the  highest  number  available.  Currently the only commands that understand ranges are GroupMarkThdRead
       ('K'), MarkArtUnread ('z') and MarkThdUnread ('Z').

   NEWSGROUP LISTS & WILDCARDS
       Several places in tin allow you to specify a list  of  newsgroups.  These  include  command-line  groups,
       (un)subscribe groups, the AUTO[UN]SUBSCRIBE mechanism. The scope= attributes file tag and the filter file
       group= tag also use the same syntax. tin interprets this variable similarly to rn(1).  It contains a list
       of  patterns,  separated  by  commas  and possibly prefixed with exclamation points. An exclamation point
       negates the meaning of a match on this pattern, and can be used to cancel certain matches. Some examples:

       alt.config,news.*,!news.test

       Matches alt.config and everything in the 'news' hierarchy except news.test

       See the explanation for the $AUTOSUBSCRIBE variables for further examples.

   SIGNATURES
       tin    will    recognize    a    signature    in     either     ${TIN_HOMEDIR:-"$HOME"}/.signature     or
       ${TIN_HOMEDIR:-"$HOME"}/.Sig.   If  ${TIN_HOMEDIR:-"$HOME"}/.signature exists, then the signature will be
       pulled into the editor for mail commands only. A signature in ${TIN_HOMEDIR:-"$HOME"}/.signature will not
       be pulled into the editor for posting commands since inews(1) will append the signature itself.

       A  signature  in ${TIN_HOMEDIR:-"$HOME"}/.Sig will be pulled into the editor for both posting and mailing
       commands.

       The following is an example of a .Sig file:
              NAMES  Joe Bar <joe@example.org>
              SNAIL  Musterweg 12, 99999 Notreal, Germany

       tin also has the capability to generate random signatures on a per newsgroup basis if so desired. The way
       to  accomplish this is to specify the default signature or the group attribute sigfile as a directory. If
       for example the sigfile path is /usr/iain/.sigs and .sigs is a directory then tin will  select  a  random
       signature  from any file that is in the directory .sigs (note: one signature per numbered file). A random
       signature can also consist of a fixed part signature that can contain your name, address etc. followed by
       the random sig. The fixed part of the random sig is read from the file $HOME/.sigfixed.

   CUSTOMIZING THE SCREEN FORMAT
       The  look  of  the  Selection,  Group and Thread level can be customized via format strings. These format
       strings define the content and the position of each element on the screen. Variables are used within  the
       format strings as placeholders. The following variables are available:

          %D    date
          %F    from, name and/or address
          %G    newsgroup name
          %I    initials
          %L    line count
          %M    message-id
          %R    number of responses in thread
          %S    score
          %T    thread tree
          %U    unread count
          %d    newsgroup description
          %f    newsgroup flag
          %m    article marks
          %n    current group/thread/article number
          %s    subject
          %%    %

       Not all variables can be used in each level. The following table provides an overview:

              select_format group_format thread_format
          %D                      X            X
          %F                      X            X
          %G        X
          %I                      X            X
          %L                      X            X
          %M                      X            X
          %R                      X
          %S                      X            X
          %T                                   X
          %U        X
          %d        X
          %f        X
          %m                      X            X
          %n        X             X            X
          %s                      X
          %%        X             X            X

       Defaults for the format strings:

          select_format: "%f %n %U  %G  %d"
          group_format:  "%n %m %R %L  %s  %F"
          thread_format: "%n %m  [%L]  %T  %F"

       show_description  controls whether the newsgroup description is shown or not. The description can also be
       toggled with SelectToggleDescriptions ('d').

       The information displayed with '%F' depends on the value  of  show_author.  GroupToggleSubjDisplay  resp.
       ThreadToggleSubjDisplay ('d') switches through all available options.

       ’%D' uses date_format for date representation. It is possible to specify a different date format in round
       brackets (e.g. '%(%d %b %y %H:%M)D'). See date_format for more details.

       The length of each item (except '%%') can be defined with a positive number after the '%'. The  following
       example  displays  the  score  in  the  thread level 10 characters wide: '%10S'. Some variables do have a
       default width which may lead to truncation. Truncation for variables which contain only  numbers  happens
       by  dividing  the  value  with  a  sufficient power of ten and adding a SI suffix to the result, i.e. the
       variable holds a value of 54321 and the width for the variable is 4 the result will be "54 k". If  that's
       undesired you have to specify a larger width manually, i.e. '%6n'. Here is an overview of the defaults:

          Variable  width
          %I         3
          %L         4
          %M        10
          %R         3
          %S         6
          %U         5
          %n         4

       If  no  length is given for '%D', the length is determined by the format string for the date and the date
       of the current day. If the date format string contains weekdays or months names it may  happen  that  the
       date  is  longer  than  determined in the first pass. In this case, the date is truncated before display.
       This occurs, for example, if the current month is May and the article to which the date is displayed  was
       posted  in  December.  In such cases it might useful to determine the maximum length manually and specify
       the length in the format string.

       When the format string contains the specifier '%F' and '%s' resp. '%T' and no length are given, '%F' will
       use one third and '%s' resp. '%T' will use two third of the available space.

       In  addition,  a  minimum screen width can be defined for each item (except ’%%'). In this case, the item
       will only be displayed when the screen is wider than specified. This comes in handy  to  not  overload  a
       small screen but have maximum information on a large screen. The minimum screen width has to be specified
       by a positive number preceded by an '>'. In the following example tin will display the score only if  the
       screen is wider than 100 characters: '%>100S'.

       If  both  the length and the minimum screen width should be specified for an item, the length must be the
       first parameter and the minimum screen width must be the second one. The following example  displays  the
       score with a length of 10 characters only if the screen is wider than 100 characters: ’%10>100S'.

   TIPS AND TRICKS
       tin  can  be pretty much be navigated by using the four cursor keys.  The left arrow key goes up a level,
       the right arrow key goes down a level, the up arrow key goes up a line and the down arrow key goes down a
       line.

       The following newsgroups provide useful information concerning news software:
           —news.software.readers (info. about news user agents tin, rn, nn, slrn etc.)
           —news.software.nntp (info. about NNTP)
           —news.answers (Frequently Asked Questions (FAQ) about many different themes)

       Many  prompts  within tin offer a default choice that the cursor is positioned on. By pressing '<CR>' the
       default value is taken.  Most prompts can be aborted by pressing '<ESC>'.

       When tin is run in an xterm(1x) it will resize itself each time the xterm(1x) is resized.

       tin  will  reread  the  ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}  file  at   set   intervals
       (reread_active_file_secs) to show any newly arrived news.

       If  you  find  large number of new newsgroups cluttering up your screen, pressing SelectToggleReadDisplay
       ('r') will make them go away.

   XTERM BUTTONS
       If the environment variable $TERM is set to xterm(1x), then button pressing can be used to select  groups
       and articles. In this discussion, the buttons are assumed to be assigned conventionally (i.e., Button1 is
       the left button).

       In general (i.e., for the group, thread and article menus),

       Button1 (left)
                 enters next (lower) level if you click on an article, otherwise pages down.

       Button2 (center)
                 returns to the previous (upper) level if you click on an article, otherwise pages up.

       Button3 (right)
                 positions on the article line under mouse cursor, or pages down if you've clicked  outside  the
                 list of articles.

       In the group selection menu, if the mouse is pointing at a group then:

       left button
                 moves to and selects the group pointed at, just like SelectReadGrp ('<CR>').

       center button
                 quits the program, just like Quit ('q').

       right button
                 moves to the group pointed at.

       In the article menu, if the mouse is pointing at an article (or thread) then:

       left button
                 reads  the  article  pointed at, just like GroupReadBasenote ('<CR>'), or the thread, just like
                 GroupListThd ('l').

       center button
                 exits the menu, catching up on  the  group  if  you  have  group_catchup_on_exit  set  in  your
                 configuration, just like Quit ('q').

       right button
                 moves to the article (or thread) pointed at.

       In the thread menu, if the mouse is pointing at an article then:

       left button
                 reads article pointed at, just like ThreadReadArt ('<CR>').

       center button
                 exits  the  menu,  catching  up  on  the  thread if you have thread_catchup_on_exit set in your
                 configuration, just like Quit ('q').

       right button
                 moves to the article pointed at.

       In other menus and areas button pressing reverts back to usual cut and paste of xterm(1x), but after  one
       click of any button.

   INDEX FILES
       If  your  news  server supports NOV index files (see newsoverview(5), most modern installations will) and
       you have a fast connection to your news server then this section can be ignored.

       If your news server doesn't support NOV index files or you have a  very  slow  connection  to  your  news
       server  then  tin can cache the index for each newsgroup if cache_overview_files is set to ON.  Note that
       this cache can use up large amounts of disk space if you read a lot of groups and/or high traffic groups.

       Each    user    creates/updates    his/her     own     index     files     that     are     stored     in
       ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news/.  If  you  are reading via NNTP then the news
       server name will be appended to keep the indexes for different servers separate. If you are  reading  off
       the  local  spool  and  local  overview  files already exist then turning on caching will have no effect.
       Likewise unless you see significant delays entering a group when reading via NNTP then turning on caching
       will have little or no effect.

       Entering  a  group  the first time tends to be slow because the index file must be built from scratch. To
       alleviate the slowness start tin to create all index files for the groups you subscribe to with tin -u -v
       and  go  for  a  coffee.  Subsequent readings of a group will only need to do incremental updating of the
       index file and will be much faster as only new articles will need to be cached.

       As indexing might take some time you may want to run tin form the system batcher cron(1) with the  ''-u''
       option:

              30 6 * * * /usr/local/bin/tin -u

       If  you  are low on local disk space you should consider to manually purge cached data for groups you are
       not reading anymore with something like:

              find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
              -type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT

       TINRC  Define this variable if you want to specify command-line options that tin should be  started  with
              to save typing them each time it is started. The contents of the environment variable are added to
              the front of the command-line options before it is parsed therefore allowing an  option  specified
              on the command-line to override the same option specified in the environment.

       TIN_HOMEDIR
              Define  this variable if you do not want the .tin directory in $HOME/. E.g., if you want all tin's
              private files in /tmp/.tin you would set $TIN_HOMEDIR to /tmp.

       TIN_INDEX_NEWSDIR
              Define this variable if you do not want  the  .news  directory  in  ${TIN_HOMEDIR:-"$HOME"}/.tin/.
              E.g.,  if  you  want  all tin's news index files in /tmp/.news you would set $TIN_INDEX_NEWSDIR to
              /tmp.

       TIN_INDEX_MAILDIR
              Define this variable if you do not want  the  .mail  directory  in  ${TIN_HOMEDIR:-"$HOME"}/.tin/.
              E.g.,  if  you  want  all tin's mail index files in /tmp/.mail you would set $TIN_INDEX_MAILDIR to
              /tmp.

       TIN_INDEX_SAVEDIR
              Define this variable if you do not want  the  .save  directory  in  ${TIN_HOMEDIR:-"$HOME"}/.tin/.
              E.g.,  if  you  want  all tin's save index files in /tmp/.save you would set $TIN_INDEX_SAVEDIR to
              /tmp.

       TIN_LIBDIR
              Define this variable if you want to override the NEWSLIBDIR path that was compiled  into  the  tin
              binary,  default  is  /usr/lib/news.   If tin is running in NNTP mode setting this variable has no
              effect.

       TIN_SPOOLDIR
              Define this variable if you want to override the SPOOLDIR path that  was  compiled  into  the  tin
              binary,  default  is /var/spool/news.  If tin is running in NNTP mode setting this variable has no
              effect.

       TIN_NOVROOTDIR
              Define this variable if you want to override the NOVROOTDIR path that was compiled  into  the  tin
              binary,  default is SPOOLDIR (see above). If tin is running in NNTP mode setting this variable has
              no effect.

       TIN_NOVFILENAME
              Define this variable if you want to override the OVERVIEW_FILE file name that  was  compiled  into
              the  tin binary, default is .overview. If tin is running in NNTP mode setting this variable has no
              effect.

       TIN_ACTIVEFILE
              Define this variable if you want to override the NEWSLIBDIR/active path that was compiled into the
              tin  binary. If tin is running in NNTP mode setting this variable has no effect. If $TIN_LIBDIR is
              set it is prepended to $TIN_ACTIVEFILE.

       NNTPSERVER
              The default NNTP server to remotely read news from. This variable only needs  to  be  set  if  the
              ''-r''  command-line  option is specified and the file /etc/news/server does not exist. The ''-g''
              command line option overrides $NNTPSERVER.

       NNTPPORT
              The NNTP TCP-port to read news from. This variable only needs to be set if the TCP-port is not 119
              (the default).  The ''-p'' command-line option overrides $NNTPPORT.

       DISTRIBUTION
              Set  the  article  header  field  ''Distribution:'' to the contents of the variable instead of the
              system default.

       ISO2ASC
              Set the ISO to ASCII charset decoding table character to use in decoding an article  text.  Values
              can range from -1 to 6.

            -1     no conversion

            0      universal table for many languages

            1      single-spacing universal table

            2      table for Danish, Dutch, German, Norwegian and Swedish

            3      table for Danish, Finnish, Norwegian and Swedish using the appropriate ISO 646 variant

            4      table with RFC1345 codes in brackets

            5      table for printers that allow overstriking with backspace

            6      table for IBM PC character set (code page 437)

       ORGANIZATION
              Set  the  article  header  field  ''Organization:'' to the contents of the variable instead of the
              system default. If reading news on an Apollo DomainOS machine the  environment  variable  $NEWSORG
              has to be used instead of $ORGANIZATION.

       NEWSORG (DomainOS)
              DomainOS specific, same as $ORGANIZATION on other OSs (see above).

       REPLYTO
              Set  the  article header field ''Reply-To:'' to the return address specified by the variable. This
              is useful if you wish to receive replies at a different address.

       NAME   Overrides the full name given in the gecos-files in /etc/passwd, see also mail_address.

       REALNAME
              Same as $NAME.

       HOME   Pathname of the user's home directory. See environ(5) for more info.

       MAILER This variable has precedence over the default mailer that is used in all mailing operations within
              tin.

       MAIL   Full path to the user's mailbox.

       VISUAL This  variable  has  precedence  over the default editor (i.e., vi(1)) that is used in all editing
              operations  within  tin  (e.g.,  posting,  replying,  follow-ups,  ...).   Evaluation   order   is
              ${VISUAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

       EDITOR If  $VISUAL is unset, then this variable is looked up for a default editor. If $EDITOR and $VISUAL
              are both unset, tin uses the systems default editor (i.e.  vi(1)) on UNIX-systems). See environ(5)
              for more info.

       AUTOSUBSCRIBE
              A new group is checked against the list of patterns; if it matches, tin subscribes the user to the
              group without further query.  See the section "NEWSGROUP LISTS & WILDCARDS" for an explanation  of
              the valid syntax. For example, setting

              AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

              will  automatically  subscribe  the  user to all new groups in the comp.os.unix hierarchy, and all
              talk groups other than talk.politics groups (which will be queried for as usual). Of  course  this
              does not work if tin is started with the ''-X'' command-line switch.

       AUTOUNSUBSCRIBE
              Is  handled  like  the $AUTOSUBSCRIBE variable, but groups matching the list are unsubscribed from
              without further query. For example, setting

              AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

              will automatically unsubscribe the user from all new alt.flame groups and all groups starting with
              u (university groups) other than UK groups (which will be queried for as usual).

       TMPDIR A pathname of a directory made available for tin to create temporary files.

       MAILCAPS
              This  variable  can  be  used  to  override the default path search for mailcap(5) files. See also
              tin(5).

       NOMETAMAIL
              Set this variable to disable the use of metamail(1) or a replacement (e.g. metamutt).

       MM_CHARSET

       ISPELL Set this variable to point to ispell(1) or a replacement and its cmd-line options.

       PGPOPTS
              Define any additional options that you wish to pass to your pgp(1) or gpg(1) program.

       PGPPATH
              Override the name of the pgp(1) directory in $HOME that holds your keys etc..

       GNUPGHOME
              Override the name of the gpg(1) directory in $HOME that holds your keys etc..

       LC_CTYPE
              This variable determines the locale(5) category  for  character  handling  functions.  Usually  it
              determines   the  character  classes  for  pattern  matching  character  classification  and  case
              conversion. Currently this is not true for tin (which temporary unsets $LC_CTYPE right before  any
              match    is    done    to    avoid    confusion).     It's   value   should   be   of   the   form
              language[_territory][.codeset][@modifier]. See environ(5) for more information.

       LC_MESSAGES
              Formats of informative and diagnostic messages and interactive responses.  It's value should be of
              the   form  language[_territory][.codeset][@modifier].  See  locale(5)  and  environ(5)  for  more
              information.

       LC_TIME
              Date and time formats. It's value should be of the form language[_territory][.codeset][@modifier].
              See locale(5) and environ(5) for more information.

       LC_ALL This  variable  overrides  the value of the $LANG variable and any other $LC_ variable. It's value
              should be of the form  language[_territory][.codeset].  See  locale(5)  and  environ(5)  for  more
              information.

       LANG   This  variable determines the locale(5) category for any category not specifically selected with a
              variable starting with $LC_. It's value should be of the form language[_territory][.codeset].  See
              environ(5) for more information.

       LANGUAGE
              This variable defines a priority list for translations. Whenever a translation is not available in
              the language selected via $LC_ALL or $LANG the next language from the list is  tried.  It's  value
              should be of the form language:language[:language]. See environ(5) for more information.

       COLUMNS
              A  decimal  integer  >  0  used to indicate the user's preferred width in column positions for the
              terminal screen or window. If this variable is unset or null, the  implementation  determines  the
              number  of  columns,  appropriate  for the terminal or window. When $COLUMNS is set, any terminal-
              width information implied by $TERM will be overridden. Users and portable applications should  not
              set $COLUMNS unless they wish to override the system selection and produce output unrelated to the
              terminal characteristics.

       LINES  A decimal integer > 0 used to indicate the user's preferred number of  lines  on  a  page  or  the
              vertical screen or window size in lines. A line in this case is a vertical measure large enough to
              hold the tallest character in the character set being displayed. If  this  variable  is  unset  or
              null,  the  implementation determines the number of lines, appropriate for the terminal or window.
              When $LINES is set, any terminal-height information implied by $TERM will be overridden. Users and
              portable applications should not set $LINES unless they wish to override the system selection.

       TERM   The  type  of terminal in use. This is used when looking up termcap sequences.  See environ(5) for
              more information.

       DISPLAY
              Display name, pointing to the X server; required for xface.

       WINDOWID
              Used for determining terminal's X window id; required for xface. Should be  set  by  the  terminal
              emulator.

       SHELL  The pathname of the user's login shell. Used to set default_shell_command.

       XDG_RUNTIME_DIR
              The pathname of the user's dir to put non-essential runtime files into.

SIGNALS

       tin handles a couple of signals:

       SIGHUP Terminate gracefully.

       SIGTERM
              Terminate gracefully.

       SIGUSR1
              Terminate gracefully but do not restore tty.

       SIGUSR2
              Write out ${TIN_HOMEDIR:-"$HOME"}/.newsrc-file.

SECURITY

       When  tin  is  started  in debug mode (''-D n'') it will create world readable files in $TMPDIR which may
       contain the users NNTP password in cleartext. On multiuser-systems  $TMPDIR  should  be  set  to  a  safe
       location before starting tin in debug mode (e.g.  TMPDIR=$HOME tin -D 1).

CONFORMING TO

       tin  does conform to the Base Definitions volume of IEEE Std 1003.1-2008, Section 12, Utility Conventions
       (Utility Argument Syntax, Utility Syntax Guidelines).

HISTORY

       tin is based on the tass(1) newsreader that was developed by Rich Skrenta and posted  to  alt.sources  in
       March 1991; its first version was released on August 23rd 1991.  tass(1) itself was heavily influenced by
       notesfiles a public domain UNIX version of PLATO Notes, developed at the University of  Illinois  by  Ray
       Essick and Rob Kolstad in 1982. For a version overview see
       <http://www.tin.org/history.html>.
