NAME

       tin, rtin - related files

DESCRIPTION

       This  man  page  describes the various (config) files and their formats used by the tin(1)
       newsreader. All files are expected to have unix style ('\n' aka LF) line endings.

FILES

       $MAILCAPS
       ~/.mailcap
       /etc/mailcap
       /usr/etc/mailcap
       /usr/local/etc/mailcap
       /etc/mail/mailcap

              mailcap(5) files as defined in RFC1524. The mailcap files are  read  by  tin(1)  to
              determine  how to display non-text messages at the local site. Any line that starts
              with "#" is a comment. Blank lines are ignored.  Otherwise,  each  line  defines  a
              single  mailcap  entry  for  a  single content type. Long lines may be continued by
              ending them with a backslash character, "\".

              Each individual mailcap entry consists of a content-type specification,  a  command
              to execute, and (possibly) a set of optional "flag" values.

              The  "type" field is simply any legal content type name. It is the string that will
              be matched against the ''Content-Type:'' header to decide if this  is  the  mailcap
              entry  that matches the current message. Additionally, the type field may specify a
              subtype or a wildcard to match all subtypes.

              The "command" field is any UNIX command and is used to specify the interpreter  for
              the  given  type  of  message.  It  will  be  passed to the shell via the system(3)
              facility.

              Semicolons and backslashes within the command or any flag field must be quoted with
              backslashes.  If  the field contains "%s", those two characters will be replaced by
              the name of a file that contains the body of the  message.  If  it  contains  "%t",
              those  two  characters  will  be  replaced by the content-type field, including the
              subtype, if any. If it contains "%{" followed by a parameter  name  and  a  closing
              "}",  then  all  those  characters  will  be  replaced  by  the  value of the named
              parameter, if any,  from  the  ''Content-Type:''  header.  Finally,  if  the  field
              contains "\%", those two characters will be replaced by a single "%" character.

              Besides the type and command field the following "flags" are defined:

              compose
                     The  "compose"  field  may  be used to specify a program that can be used to
                     compose a new body or body part in the given format. Its intended use is  to
                     support mail composing agents that support the composition of multiple types
                     of mail using external composing  agents.  As  with  the  view-command,  the
                     semantics of program execution are operating system dependent. The result of
                     the composing program may  be  data  that  is  not  yet  suitable  for  mail
                     transport  —  that is, a Content-Transfer-Encoding may need to be applied to
                     the data.

              composetyped
                     The "composetyped" field is similar to the "compose" field,  but  is  to  be
                     used  when  the  composing  program  needs  to specify the ''Content-Type:''
                     header field to be applied to the composed  data.  The  "compose"  field  is
                     simpler, and is preferred for use with existing (non-mail-oriented) programs
                     for composing data in a given format. The "composetyped" field is  necessary
                     when the Content-Type information must include auxiliary parameters, and the
                     composition program must then know enough  about  mail  formats  to  produce
                     output that includes the mail type information.

              edit   The "edit" field may be used to specify a program that can be used to edit a
                     body or body part in the given format. In many cases, it may be identical in
                     content  to  the  "compose" field, and shares the operating-system dependent
                     semantics for program execution.

              print  The "print" field may be used to specify a program that can be used to print
                     a  message  or  body part in the given format. As with the view-command, the
                     semantics of program execution are operating system dependent.

              test   The "test" field may be used to test  some  external  condition  (e.g.,  the
                     machine  architecture,  or the window system in use) to determine whether or
                     not the mailcap line applies. It specifies a program to be run to test  some
                     condition.  The semantics of execution and of the value returned by the test
                     program are operating system dependent. If  the  test  fails,  a  subsequent
                     mailcap  entry  should  be  sought. Multiple test fields are not permitted —
                     since a test can call a program, it can already be arbitrarily complex.

              needsterminal
                     The "needsterminal" field indicates that the view-command must be run on  an
                     interactive  terminal.  This is needed to inform window-oriented user agents
                     that  an  interactive  terminal  is  needed.  (The  decision  is  not   left
                     exclusively  to the view-command because in some circumstances it may not be
                     possible for such programs to tell whether or not they  are  on  interactive
                     terminals.)  The  needsterminal  command  should  be assumed to apply to the
                     compose and edit commands, too, if they exist. Note that this is NOT a  test
                     -  it  is  a  requirement  for  the environment in which the program will be
                     executed, and should typically cause the creation of a terminal window  when
                     not executed on either a real terminal or a terminal window.

              copiousoutput
                     The  "copiousoutput"  field  indicates that the output from the view-command
                     will be an extended stream of output, and is to be interpreted as advice  to
                     the  UA  (User  Agent mail-reading program) that the output should be either
                     paged  or  made  scroll-able.  Note  that  it  is  probably  a  mistake   if
                     needsterminal and copiousoutput are both specified.

              description
                     The  "description"  field  simply provides a textual description, optionally
                     quoted, that describes the type of data,  to  be  used  optionally  by  mail
                     readers that wish to describe the data before offering to display it.

              textualnewlines
                     The  "textualnewlines"  field,  if set to any non-zero value, indicates that
                     this type of data is line-oriented and  that,  if  encoded  in  base64,  all
                     newlines  should  be converted to canonical form (CRLF) before encoding, and
                     will be in that form after decoding. In general, this field is  needed  only
                     if  there  is line-oriented data of some type other than text/* or non-line-
                     oriented data that is a subtype of text.

              x11-bitmap
                     The "x11-bitmap" field names a file,  in  X11  bitmap  (xbm)  format,  which
                     points  to an appropriate icon to be used to visually denote the presence of
                     this kind of data.

              nametemplate
                     The "nametemplate" field gives a  filename  format,  in  which  %s  will  be
                     replaced  by a short unique string to give the name of the temporary file to
                     be passed to the viewing command. This is only expected to  be  relevant  in
                     environments  where  filename  extensions  are  meaningful,  e.g., one could
                     specify that a GIF file being passed to a gif  viewer  should  have  a  name
                     ending in ".gif" by using "nametemplate=%s.gif"

              tin(1) currently only respects the "test", "description", "nametemplate" and partly
              the "needsterminal" flags, all other flags are internally ignored.  It  also  can't
              handle the "%F" and "%n" expansions yet.

              Example:
                     # mailcap file example
                     image/*;\
                        xv -8 -geometry +0 '%s';\
                        description=%{name} %t-Image;\
                        test=test "$DISPLAY" != "";\
                        nametemplate=%s.IMAGE

                     message/rfc822;\
                        ${PAGER:-"more"} '%s';\
                        edit=${EDITOR:-"vi"} '%s';\
                        compose=${EDITOR:-"vi"} '%s';\
                        print=a2ps '%s';\
                        needsterminal

       /etc/news/server

              default  NNTP-server  to  read  news from if not reading from the local spool.  '-g
              server', $NNTPSERVER have higher priority (in that order), the default server given
              at compile time has lower priority.

       ${TIN_HOMEDIR:-"$HOME"}/.cancelsecret

              secret to be used for cancel-locks if tin(1) is build with support for it. An empty
              secret file disables the cancel-lock creation in that case.  This  file  should  be
              readable only by the user.

       ${TIN_HOMEDIR:-"$HOME"}/.mime.types
       /etc/mime.types
       /etc/tin/mime.types

              mime type / filename extension pairs

       ${TIN_HOMEDIR:-"$HOME"}/.newsauth

              "nntpserver  password [user]" pairs for NNTP servers that require authorization. If
              the password contains a space or a tab it must be enclosed in  double  quotes  (").
              Usernames  must  not  be enclosed in double quotes and thus can't contain spaces or
              tabs. Any line that starts with "#" is a comment. Blank  lines  are  ignored.  This
              file  should  be  readable  only for the user as it contains the user's unencrypted
              password for reading news!

              nntpserver
                     full qualified domain name of the news server.

              password
                     user's unencrypted password for reading news.

              user   username on the news server if it differs from the local login.  This  field
                     is optional.

              Example:
                     # sample .newsauth file
                     news.example.org  secret
                     news.example.net  arcane  guest
                     news.example.com  "top secret"  james.bond@example.com

       ${TIN_HOMEDIR:-"$HOME"}/.newsrc

              "newsgroupflag [article[,article | -article]...]" lines.

              newsgroup
                     the name of the newsgroup.

              flag   a flag indicating if the group is subscribed ':' or not '!'.

              article
                     range  of already read articles from that group; numbers separated by commas
                     with sequential numbers collapsed with hyphens.

              Example:
                     # sample .newsrc file
                     news.software.b! 1-666,669
                     news.software.nntp: 1-13245,13247,13249
                     news.software.readers: 1-19567,19571-19597

       ${TIN_HOMEDIR:-"$HOME"}/.tin/$NNTPSERVER${NNTPPORT:+":$NNTPPORT"}/.oldnewsrc

              backup of ${TIN_HOMEDIR:-"$HOME"}/.newsrc

       ${TIN_HOMEDIR:-"$HOME"}/.signature
       ${TIN_HOMEDIR:-"$HOME"}/.Sig

              signature

       ${TIN_HOMEDIR:-"$HOME"}/.sigfixed

              fixed part of a randomly generated signature

       ${TIN_HOMEDIR:-"$HOME"}/.tin/.inputhistory

              history of last used strings

       ${TIN_INDEX_MAILDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.mail/

              mailgroups index files

       ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news${NNTPSERVER:+"-$NNTPSERVER"}/

              newsgroups index files

       ${TIN_INDEX_SAVEDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.save/

              saved newsgroups index files

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.mail

              active file  ("mail_group_name  maxnum  minnum  mailspool"  quadruples)  of  user's
              mailgroups (requires tin(1) to be build with mh-mail-handling support).

              mail_group_name
                     must be the pathname of the mailbox relative to field #4 with / changed to .

              maxnum just  put  a large number here, something higher than the highest message in
                     the mailbox

              minnum put 0 here

              mailspool
                     path of mail spool directory. This must be the full pathname to the root  of
                     the mail folder area.

              Example:
                     Mail.inbox  12345 00000 /home/foo
                     Mail.outbox 23456 00000 /home/foo

              This  allows  access  to  the  'inbox'  and 'outbox' folders of user foo.  They are
              accessed via /home/foo/Mail/inbox and /home/foo/Mail/outbox

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.save

              active file of user's saved newsgroups, used by tin -R.

       /etc/tin/attributes
       ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes

              The group attributes files may be  used  to  override  some  global  settings  from
              ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc on a per group basis. Order is important as last
              match counts; this allows one to refine attributes for narrowed scopes.  Note  that
              the  scope=<grouplist> line has to be specified before the attributes are specified
              for that list and each attribute can only  be  set  once  per  scope  section.  All
              attributes  are  set  to  a  reasonable  default  so  you  only have to specify the
              attribute that you want to change. All toggle  attributes  are  set  by  specifying
              ON/OFF. Otherwise, they function exactly as their global equivalents. The following
              group attributes are available:

              scope  This changes the list of groups to which the attributes that follow will  be
                     applied. See the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types
                     of pattern that can be used here.

                     Determines whether usenet articles are forwarded as  attachment  or  inline.
                     When  set  to OFF, the forwarded article will be included in the body of the
                     mail, while setting this variable  to  ON  will  cause  the  article  to  be
                     attached  as  a  separate  MIME  part. Enabling mime_forward is particularly
                     useful for articles consisting of  multiple  MIME  parts  such  as  PGP/MIME
                     signed  messages  or  being  encoded  in a different character set than your
                     local one. It is also useful if the receiver should be able  to  operate  on
                     the  entire forwarded article (i.e., view or save it without your comments).
                     On the other hand, if you want to forward only some parts of the article  or
                     to  insert  'inline'  annotations,  you  might  want to disable this option.
                     Currently mime_forward is  forced  if  the  article  to  be  attached  is  a
                     multipart  MIME  article,  this may change in a future version.  Please note
                     that for this option to have effect, the tinrc  variable  interactive_mailer
                     has to be set to 0 (which is the default).

              mime_types_to_save
                     A  comma separated list of MIME major/minor Content-Types that will be saved
                     when using the view/save and save/autosave features.  A single * can be used
                     to wildcard the major and/or minor type and a ! as the first character in an
                     entry will negate it, eg: image/*,!image/bmp,!text/html. Default is */*

              organization
                     This can be used to set  the  article  header  field  ''Organization:''.  It
                     overrides  the setting (if any) of organization in /etc/tin/tin.defaults and
                     $ORGANIZATION (or $NEWSORG on Apollo DomainOS). Note that some news  servers
                     might still overwrite the ''Organization:'' header.

                     is assumed to be the name of a file containing the header and its content to
                     be inserted. If the string starts with a ! then what follows is  assumed  to
                     be  the  path  to  a  program  to be executed to generate the header and its
                     content. %G is expanded to the current news.group.name and %P is expanded to

              undeclared_charset
                     Assume (broken) articles without MIME charset declaration have this  charset
                     —  default  is  US-ASCII.  This attribute works only on systems with working
                     iconv(3),    others    might     have     to     compile     tin(1)     with
                     --disable-mime-strict-charset.

              Example:
                     # include extra headers
                     # assume ISO-8859-1 as charset if no charset is declared

       ${TIN_HOMEDIR:-"$HOME"}/.tin/filter

              The filter file is used to assign scores to certain articles. Based on the score an
              article can be filtered out (hidden) or marked hot. Empty lines or lines  beginning
              with a '#' are ignored.

              comment
                     Every  entry  (rule)  in the filter file might get a comment. Multiple lines
                     are allowed (but only for comments yet). Every  line  must  start  with  the
                     "comment="  keyword.  Comments must appear first in the rule.  Comment lines
                     placed within a rule will be moved to the begin of the next rule. This might
                     be  changed in the future. Don't use '#' to mark comments as those lines are
                     ignored and your comments will get lost on the next write of the file.

              group  A comma-separated list of newsgroup patterns (wildmat-style) to which groups
                     the filter rule will be applied. This line is mandatory!

              case   0=case-sensitive, 1=case-insensitive

              score  Score value of the rule; can also be one of the magic words "kill" or "hot".

              subj   Match against ''Subject:''

              from   Match  against  ''From:''.   tin(1)  converts  the contents of the ''From:''
                     header to an old style e-mail address, e.g. ''some@body.example (John Doe)''
                     instead  of  ''John  Doe  <some@body.example>'',  before trying to match the
                     patterns in the filter rule.

              msgid  Match against ''Message-ID:'' and full ''References:''

              msgid_last
                     Match against ''Message-ID:'' and last ''References:'' entry only

              msgid_only
                     Match against ''Message-ID:''

              refs_only
                     Match against ''References:''

              lines  Match against ''Lines:'', <num matches less than, >num matches more than.

              gnksa  Match against ''From:'' address parser return codes.

              xref   Match against ''Xref:'' line. Before any matching is done the line is turned
                     into  the  same format ''Newsgroups:'' has that is it is turned into a comma
                     separated newsgroup list with  all  other  information  (i.e.   the  article
                     counter) removed.

              path   Match against ''Path:'' line. This may not work on some servers.

              time   time_t value when rule expires

              Example:
                     comment=mark all articles about tin, rtin,
                     comment=tind, ktin or cdtin as hot

                     getart_limit. Default is 0, which means no limit.

              goto_next_unread
                     Which  keys  %tin(1)  should  accept  to  jump  to  the next unread article.
                     Possible is any combination of PageDown and PageNextUnread.   When  PageDown
                     is set %tin(1) jumps to the next article at the end of the current one. When
                     PageNextUnread is set %tin(1) jumps immediately to  the  next  article  when
                     PageNextUnread ('<TAB>') is pressed. Default is PageNextUnread.

                        %I    initials
                        %L    line count
                        %M    message-id
                        %R    number of responses in thread
                        %S    score
                        %m    article marks

              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'.

              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.

              interactive_mailer
                     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.

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

              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.

              kill_level
                     This option controls the processing and display of articles that are killed.
                     There are 3 options, default is 0 (Kill only unread arts).

                        0  Kill only unread arts is the 'traditional' behavior of  tin(1).   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.

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

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

              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:"

              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.

              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.

              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
                        sendmail -oem -t < %F
                        elm -s "%S" "%T" < "%F"
                        claws-mail --compose "mailto:%T?subject=%S&insert=%F"
                     interactive_mailer must be set adequate.  The  following  substitutions  are
                     supported:
                        %F              filename
                        %M              default_mailer
                        %S              subject-field
                        %T              to-filed
                        %U              username

              mark_saved_read
                     If ON mark articles that are saved as read. Default is ON.

              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.

              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
                     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
                     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.

              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.

              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.

              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.

              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(1) to keep track of new newsgroups. Do
                     not change them unless you understand what they are for.

              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.

              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.

              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_secs
                     Time in seconds to wait for a response from the server. Default is 120.

              normalization_form
                     The normalization form which should be used 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

                        5  NFKC_CF:    Compatibility   Decomposition,   followed   by   Canonical
                           Composition and Case Folding
              Some normalization modes are only available if they are supported  by  the  library
              tin(1) uses to do the normalization. NFC should be used if possible.

              pos_first_unread
                     If ON put cursor at first unread article in group otherwise at last article.
                     Default is ON.

              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.

              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.

              post_process_view
                     If  ON,  then tin(1) will start an appropriate viewer program to display any
                     files that were post processed and  uudecoded.  The  program  is  determined
                     using the mailcap(5) file. Default is ON.

              post_process_type
                     This  specifies  whether  to  perform  post  processing  on  saved articles.
                     Because the shell archive may contain  commands  you  may  not  want  to  be
                     executed,  be  careful when extracting shell archives.  The following values
                     are allowed:

                        0  No (default), no post processing is done.

                        1  Shell archives, unpacking of multi-part shar(1)  files  only.  Because
                           the  shell  archive  may  contain  commands  you  may  not  want to be
                           executed, be careful with this option.

                        2  Yes, binary attachments and data will be decoded and saved.

              posted_articles_file
                     Keep posted articles  in  ${TIN_HOMEDIR:-"$HOME"}/Mail/posted_articles_file.
                     If no filename is set then postings will not be saved.  Default is 'posted'.

              print_header
                     If  ON,  then the full article header is sent to the printer. Otherwise only
                     the ''Subject:'' and ''From:'' fields are output. Default is OFF.

              printer
                     The printer program with options that is to be used to print  articles.  The

              quote_chars
                     The character used in quoting included text to article  followups  and  mail
                     replies. The '_' character represents a blank character and is replaced with
                     ' ' when read. Default is '>_'.

              quote_style
                     This bit coded integer value controls how articles are  to  be  quoted  when
                     following  up  or  replying  to  them.  Any  of the following options can be
                     combined by adding all relevant values. Default is 5, which means that quote
                     characters are compressed and empty lines are quoted.

                        1  Compress  quotes  Compress  quote  characters  together  when  quoting
                           multiple times (for example, '> > >' will be turned into '>>>').  This
                           option is on by default.

                        2  Quote  Signatures This option is off by default. Signatures are always
                           quoted regardless of this option when you are viewing  an  article  in
                           raw  mode PageToggleRaw ('^H') and followup or reply to it. Signatures
                           are never quoted regardless of this  option  when  show_signatures  is
                           off.

              quote_regex
                     A  regular  expression  that  will  be  applied  when  reading articles. All
                     matching lines are shown in col_quote. If quote_regex is blank, then  tin(1)
                     uses a built-in default.

              quote_regex2
                     A  regular  expression  that  will  be  applied  when  reading articles. All

                     tin(1) uses a built-in default.

              quote_regex3
                     A  regular  expression  that  will  be  applied  when  reading articles. All
                     matching lines are shown in  col_quote3.  If  quote_regex3  is  blank,  then
                     tin(1) uses a built-in default.

              recent_time
                     If  set  to 0, this feature is deactivated, otherwise it means the number of
                     days. Default is 2.

              render_bidi
                     If ON %tin(1) does the rendering of  bi-directional  text.  If  OFF  %tin(1)

                     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.

              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_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.

              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.

              wrap_on_next_unread
                     If  enabled  a  search  for  the  next  unread  article will wrap around all
                     articles to find also previous unread articles. If disabled the search stops
                     at the end of the thread list. Default is ON.

              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.

       /etc/tin/tin.defaults

              Yet another global configuration file with "variable=value" pairs. This one is  for
              the    more    general    options   which   usually   can't   be   controlled   via
              ${TIN_LIBDIR:-NEWSLIBDIR}/tinrc  and/or   ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc   like
              resetting (to override the built-in default) the newslibdir.

              domainname
                     Sets a global domain name used in From lines

              organization

                     overrides any specified value.

              bugaddress
                     Defines the email address to which users can send bug reports using a built-
                     in  function.  The  default  points  to a developers mailing list located at
                     tin.org. You might want  to  change  this  address  to  one  of  your  local
                     administration if you want to deal with your lusers problems on your own.

              inewsdir
                     Defines the directory containing the inews(1) executable.

              post_mime_encoding
                     Default encoding scheme used in MIME articles. 8bit might be the best value.

              mail_mime_encoding
                     Default encoding scheme used in MIME letters.  quoted-printable  is  a  good
                     choice here.

              disable_gnksa_domain_check
                     Allow unregistered top level domains. As the list of valid TLDs is no longer
                     actively maintained the default was  changed  to  ON  starting  with  tin(1)
                     version 2.1.5

              disable_sender
                     Don't  generate  a ''Sender:'' header. This has an effect only if inews_prog
                     is set to --internal.

              spooldir

              overviewdir
                     Base of your NOV database newsoverview(5) (tradspool  style;  might  be  the
                     same    dir   as   spooldir),   common   values   are   /var/spool/overview,
                     /usr/spool/overview, /news/overview. $TIN_NOVROOTDIR overrides any specified
                     value.

              overviewfile
                     Name  of  a  single  overview  file, common values are .overview, over.view.
                     $TIN_NOVFILENAME overrides any specified value.

              overviewfmtfile
                     Full  pathname  of  your  newssystem's  overview.fmt   file;   usually   the

                     specified value.

              activetimesfile
                     Full   pathname   of   your  newssystem's  active.times  file;  usually  the
                     active.times file is newslibdir, so you only have to change this setting  if

              newsgroupsfile
                     Full  pathname  of your newssystem's newsgroups file; usually the newsgroups
                     file is in newslibdir, so you only have  to  change  this  setting  if  your

       /usr/local/share/locale/$LC_MESSAGES/LC_MESSAGES/tin.mo

              translation into language specified in $LC_ALL, $LC_MESSAGES or $LANG

       ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}

              This  file lists the newsgroups that the local site receives. Each newsgroup should
              be listed only once. Each line specifies one group; within each newsgroup, articles
              are assigned unique names, which are monotonically increasing numbers.

              If  an article is posted to newsgroups not mentioned in this file, those newsgroups
              are ignored.  If no valid newsgroups are specified, the article is rejected.

              Each line consists of four space-separated fields "name highmark lowmark flags".

              name   is the name of the newsgroup

              highmark
                     is the highest article number that has been used in that newsgroup

              lowmark
                     is the lowest article number in the group; this number is not guaranteed  to
                     be  accurate,  and  should  only be taken to be a hint. Note that because of
                     article cancellations, there may be gaps in the numbering sequence.  If  the
                     lowest article number is greater than the highest article number, then there
                     are no articles in the newsgroup.

              flags  can be one of those

                     y      local postings are allowed

                     n      no local postings are allowed, only remote ones

                     m      the group is moderated and all postings must be approved

                     j      articles in this group are not kept, but only passed on

                     x      articles cannot be posted to this newsgroup

                     =foo.bar
                            articles are locally filed into the ''foo.bar'' group

              tin(1) only tries to read the file if you read directly from the  local  spool,  if
                     you  read news via NNTP, tin(1) uses the LIST (RFC3977) or LIST COUNTS (RFC‐
                     6048) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/active.times

              This file provides a chronological record of when newsgroups  are  created.  It  is
              normally  updated  by the local news server (e.g.  innd(8)) whenever a new group is
              created. Each line consist of three space-separated fields "name time creator".

              name   is the name of the newsgroup

              time   is the time when the group was created, expressed as the number  of  seconds
                     since the Epoch.

              creator
                     is the electronic mail address of the person who created the group.

              tin(1) only  tries  to  read the file if you read directly from the local spool, if
                     you read news via NNTP, tin(1) uses the NEWGROUPS (RFC3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups

              This file provides short descriptions of each newsgroup. It is normally updated  by
              the  local  news  server (e.g.  innd(8)) whenever a new group is created. Each line
              consist of two tab-separated fields "group.name             one-line description".

              group.name
                     is the name of the newsgroup

              one-line description
                     is a short single-line description of the group

              tin(1) only tries to read the file if you read directly from the  local  spool,  if
                     you  read  news  via NNTP, tin(1) uses the LIST NEWSGROUPS (RFC3977) command
                     instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/organization

              This file might hold a default organization to be  used  in  the  ''Organization:''
              header. $ORGANIZATION has a higher priority if set.

       ${TIN_LIBDIR:-NEWSLIBDIR}/overview.fmt

              This  file  specifies  the  organization  of  the  news overview database (see also
              newsoverview(5)).  The order of lines in this file is important; it determines  the
              order  in  which  the fields will appear in the database. See also overview.fmt(5).
              tin(1) only tries to read the file if you read directly from the  local  spool,  if
              you  read  news  via  NNTP,  tin(1)  uses  the  LIST OVERVIEW.FMT (RFC3977) command
              instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions

              This file contains a list of newsgroups — one per line — which  the  client  should
              subscribe  to  when  the  user  has no ${TIN_HOMEDIR:-"$HOME"}/.newsrc for the news
              server.  tin(1) only tries to read the file if you read  directly  from  the  local
              spool,  if  you  read  news  via NNTP, tin(1) uses the LIST SUBSCRIPTIONS (RFC6048)
              command instead.
