DESCRIPTION

       Lynx is a fully-featured World Wide Web (WWW) client for users running cursor-addressable,
       character-cell display devices (e.g., vt100 terminals, vt100 emulators running on  Windows
       95/NT  or Macintoshes, or any other "curses-oriented" display).  It will display hypertext
       markup language (HTML) documents containing links to files residing on the  local  system,
       as  well  as  files  residing  on remote systems running Gopher, HTTP, FTP, WAIS, and NNTP
       servers.  Current versions of Lynx run on Unix, VMS, Windows 95/NT, 386DOS and OS/2 EMX.

       Lynx can be used to access information on the World Wide  Web,  or  to  build  information
       systems  intended  primarily  for  local access.  For example, Lynx has been used to build
       several Campus Wide Information Systems (CWIS).  In addition, Lynx can be  used  to  build
       systems isolated within a single LAN.

OPTIONS

       At  start  up,  Lynx will load any local file or remote URL specified at the command line.
       For help with URLs, press "?"  or "H" while running Lynx.  Then follow  the  link  titled,
       "Help on URLs."

       If  more  than  one local file or remote URL is listed on the command line, Lynx will open
       only the last interactively.  All of the names (local files and remote URLs) are added  to
       the G)oto history.

       Lynx  uses  only  long  option  names.  Option  names  can begin with double dash as well,
       underscores and dashes can be intermixed in option names (in the reference  below  options
       are with one dash before them and with underscores).

       Lynx  provides many command-line options.  Some options require a value (string, number or
       keyword).  These are noted in the reference below.  The other options set  boolean  values
       in  the  program.  There are three types of boolean options: set, unset and toggle.  If no
       option value is given, these have the obvious meaning: set (to true), unset (to false), or
       toggle  (between  true/false).   For  any  of  these,  an  explicit  value can be given in
       different forms to allow for operating system constraints, e.g.,
              -center:off
              -center=off
              -center-
       Lynx recognizes "1", "+", "on" and "true" for true values, and "0", "-", "off" and "false"
       for false values.  Other option-values are ignored.

       The  default  boolean,  number  and  string  option values that are compiled into Lynx are
       displayed in the help-message provided by lynx -help.  Some of those may differ  according
       to  how Lynx was built; see the help message itself for these values.  The -help option is
       processed in the third pass of options-processing, so any option which sets  a  value,  as
       well as runtime configuration values are reflected in the help-message.

       -      If  the  argument  is only '-', then Lynx expects to receive the arguments from the
              standard input.  This is to allow for the potentially very long command  line  that
              can  be  associated with the -get_data or -post_data arguments (see below).  It can
              also be used to avoid having sensitive information in  the  invoking  command  line
              (which  would  be  visible to other processes on most systems), especially when the
              -auth or -pauth options are used.

       -accept_all_cookies
              accept all cookies.

       -anonymous
              apply restrictions for anonymous account, see also -restrictions.

       -assume_charset=MIMEname
              charset for documents that don't specify it.

       -assume_local_charset=MIMEname
              charset assumed for local files, i.e., files which Lynx creates  such  as  internal
              pages for the options menu.

       -assume_unrec_charset=MIMEname
              use this instead of unrecognized charsets.

       -auth=ID:PASSWD
              set  authorization  ID and password for protected documents at startup.  Be sure to
              protect any script files which use this switch.

       -base  prepend a request URL comment and BASE tag to text/html outputs for -source dumps.

       -bibp=URL
              specify a local bibp server (default http://bibhost/).

       -blink forces high intensity background colors for color mode, if available and  supported
              by the terminal.  This applies to the slang library (for a few terminal emulators),
              or to OS/2 EMX with ncurses.

       -book  use the bookmark page as the startfile.  The default or command line  startfile  is
              still  set  for  the  Main screen command, and will be used if the bookmark page is
              unavailable or blank.

       -buried_news
              toggles scanning of news articles for buried references, and converts them to  news
              links.   Not recommended because email addresses enclosed in angle brackets will be
              converted to false news links, and uuencoded messages can be trashed.

       -cache=NUMBER
              set the NUMBER of documents cached in memory.  The default is 10.

       -case  enable case-sensitive string searching.

       -center
              Toggle center alignment in HTML TABLE.

       -cfg=FILENAME
              specifies a Lynx configuration file other than the default lynx.cfg.

       -child exit on left-arrow in startfile, and disable save to disk and associated print/mail
              options.

       -child_relaxed
              exit  on  left-arrow in startfile, but allow save to disk and associated print/mail
              options.

       -cmd_log=FILENAME
              write keystroke commands and related information to the specified file.

       -cmd_script=FILENAME
              read keystroke commands from the specified file.  You  can  use  the  data  written
              using  the  -cmd_log option.  Lynx will ignore other information which the command-
              logging may have written to the logfile.  Each line of the command script  contains
              either a comment beginning with "#", or a keyword:

              exit
                 causes the script to stop, and forces Lynx to exit immediately.

              key
                 the character value, in printable form.  Cursor and other special keys are given
                 as names, e.g., "Down Arrow".  Printable 7-bit ASCII codes are given as-is,  and
                 hexadecimal values represent other 8-bit codes.

              set
                 followed  by  a  "name=value"  allows one to override values set in the lynx.cfg
                 file.

       -color forces color mode on, if available.  Default color control sequences which work for
              many  terminal  types  are  assumed if the terminal capability description does not
              specify how to handle color.  Lynx needs to be compiled with the slang library  for
              this  flag,  it  is  equivalent to setting the COLORTERM environment variable.  (If
              color support is instead provided by a color-capable curses library  like  ncurses,
              Lynx  relies completely on the terminal description to determine whether color mode
              is possible,  and  this  flag  is  not  needed  and  thus  unavailable.)   A  saved
              show_color=always  setting  found in a .lynxrc file at startup has the same effect.
              A saved show_color=never found in .lynxrc on startup is overridden by this flag.

       -connect_timeout=N
              Sets the connection timeout, where N is given in seconds.

       -cookie_file=FILENAME
              specifies a file to use to read cookies.  If none is specified, the  default  value
              is ~/.lynx_cookies for most systems, but ~/cookies for MS-DOS.

       -cookie_save_file=FILENAME
              specifies a file to use to store cookies.  If none is specified, the value given by
              -cookie_file is used.

       -cookies
              toggles handling of Set-Cookie headers.

       -core  toggles forced core dumps on fatal errors.  Turn this option off  to  ask  Lynx  to
              force a core dump if a fatal error occurs.

       -crawl with  -traversal,  output  each  page to a file.  with -dump, format output as with
              -traversal, but to the standard output.

       -curses_pads
              toggles the use of curses "pad" feature which supports left/right scrolling of  the
              display.

       -debug_partial
              separate incremental display stages with MessageSecs delay

       -delay add DebugSecs delay after each progress-message

       -display=DISPLAY
              set the display variable for X rexec-ed programs.

       -display_charset=MIMEname
              set the charset for the terminal output.

       -dont_wrap_pre
              inhibit wrapping of text in <pre> when -dump'ing and -crawl'ing, mark wrapped lines
              in interactive session.

       -dump  dumps the formatted output of the  default  document  or  those  specified  on  the
              command  line  to  standard  output.   Unlike  interactive  mode, all documents are
              processed.  This can be used in the following way:

              lynx -dump http://www.subir.com/lynx.html

       -editor=EDITOR
              enable external editing, using the specified EDITOR. (vi, ed, emacs, etc.)

       -emacskeys
              enable emacs-like key movement.

       -enable_scrollback
              toggles  compatibility  with  communication  programs'  scrollback  keys  (may   be
              incompatible with some curses packages).

       -error_file=FILE
              define a file where Lynx will report HTTP access codes.

       -exec  enable local program execution (normally not configured).

       -fileversions
              include all versions of files in local VMS directory listings.

       -find_leaks
              toggle  memory  leak-checking.  Normally this is not compiled-into your executable,
              but when it is, it can be disabled for a session.

       -force_empty_hrefless_a
              force HREF-less 'A' elements to be empty (close them as soon as they are seen).

       -force_html
              forces the first document to be interpreted as HTML.

       -force_secure
              toggles forcing of the secure flag for SSL cookies.

       -forms_options
              toggles whether the Options Menu is key-based or form-based.

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

       -get_data
              properly formatted data for a get form are read in  from  the  standard  input  and
              passed to the form.  Input is terminated by a line that starts with '---'.

       -head  send a HEAD request for the mime headers.

       -help  print the Lynx command syntax usage message, and exit.

       -hiddenlinks=[option]
              control the display of hidden links.

              merge
                 hidden  links  show up as bracketed numbers and are numbered together with other
                 links in the sequence of their occurrence in the document.

              listonly
                 hidden links are shown only on L)ist screens and listings generated by -dump  or
                 from  the P)rint menu, but appear separately at the end of those lists.  This is
                 the default behavior.

              ignore
                 hidden links do not appear even in listings.

       -historical
              toggles use of '>' or '-->' as a terminator for comments.

       -homepage=URL
              set homepage separate from start page.

              for -dump, show only the list of links.

       -localhost
              disable URLs that point to remote hosts.

       -locexec
              enable local program execution from local files only (if  Lynx  was  compiled  with
              local execution enabled).

       -lss=FILENAME
              specify  filename containing color-style information.  The default is lynx.lss.  If
              you give an empty filename, lynx uses a built-in monochrome scheme  which  imitates
              the non-color-style configuration.

       -mime_header

              immediately to window changes when run within an xterm.

       -nonumbers
              disable   link-   and   field-numbering.    This   overrides   -number_fields   and

       -restrictions=[option][,option][,option]...
              allows  a  list  of  services to be disabled selectively. Dashes and underscores in
              option names can be intermixed. The following list is printed  if  no  options  are
              specified.

              all
                 restricts all options listed below.

              bookmark
                 disallow changing the location of the bookmark file.

                 disallow execution links via the bookmark file.

              change_exec_perms
                 disallow  changing  the  eXecute  permission  on  files  (but still allow it for
                 directories) when local file management is enabled.

              default
                 same as command line option -anonymous.  Disables default services for anonymous

                 disallow  rlogins  for  people coming from inside your domain (utmp required for
                 selectivity).

              inside_telnet
                 disallow telnets for people coming from inside your domain  (utmp  required  for
                 selectivity).

              outside_ftp
                 disallow  ftps  for  people  coming  from outside your domain (utmp required for
                 selectivity).

              outside_news
                 disallow USENET news reading and posting for people  coming  from  outside  your
                 domain  (utmp  required  for  selectivity).  This restriction applies to "news",
                 "nntp", "newspost", and "newsreply" URLs, but not to  "snews",  "snewspost",  or
                 "snewsreply" in case they are supported.

       -resubmit_posts
              toggles  forced  resubmissions  (no-cache)  of  forms  with  method  POST  when the
              documents they returned are sought with the PREV_DOC command or  from  the  History
              List.

       -rlogin
              disable recognition of rlogin commands.

       -scrollbar
              toggles showing scrollbar.

       -scrollbar_arrow
              toggles showing arrows at ends of the scrollbar.

       -selective
              require .www_browsable files to browse directories.

       -session=FILENAME
              resumes from specified file on startup and saves session to that file on exit.

       -sessionin=FILENAME
              resumes session from specified file.

       -sessionout=FILENAME
              saves session to specified file.

       -short_url
              show  very  long  URLs in the status line with "..." to represent the portion which
              cannot be displayed.  The beginning and end of the URL are displayed,  rather  than
              suppressing the end.

       -show_cfg
              Print the configuration settings, e.g., as read from "lynx.cfg", and exit.

       -show_cursor
              If  enabled the cursor will not be hidden in the right hand corner but will instead
              be positioned at the start of the currently selected  link.   Show  cursor  is  the
              default  for  systems without FANCY_CURSES capabilities.  The default configuration
              can be changed in userdefs.h or lynx.cfg.  The  command  line  switch  toggles  the
              default.

       -show_rate
              If  enabled  the  transfer rate is shown in bytes/second.  If disabled, no transfer
              rate is shown.  Use lynx.cfg or the options menu to select KB/second and/or ETA.

       -soft_dquotes
              toggles emulation of the old Netscape and Mosaic bug which treated  '>'  as  a  co-
              terminator for double-quotes and tags.

       -source
              works  the  same  as  dump  but outputs HTML source instead of formatted text.  For
              example

              lynx -source . >foo.html

              generates HTML source listing the files in the current  directory.   Each  file  is
              marked  by  an HREF relative to the parent directory.  Add a trailing slash to make
              the HREF's relative to the current directory:

              lynx -source ./ >foo.html

       -stack_dump
              disable SIGINT cleanup handler

       -startfile_ok
              allow non-http startfile and homepage with -validate.

       -stderr
              When dumping a document using -dump or -source,  Lynx  normally  does  not  display
              alert  (error)  messages  that  you  see on the screen in the status line.  Use the
              -stderr option to tell Lynx to write these messages to the standard error.

       -stdin read the startfile from standard input (UNIX only).

       -syslog=text
              information for syslog call.

       -syslog-urls
              log requested URLs with syslog.

       -tagsoup
              initialize parser, using Tag Soup DTD rather than SortaSGML.

       -telnet
              disable recognition of telnet commands.

       -term=TERM
              tell Lynx what terminal type to assume it is talking to.  (This may be  useful  for
              remote  execution,  when,  for  example, Lynx connects to a remote TCP/IP port that
              starts a script that, in turn, starts another Lynx process.)

       -timeout=N
              For win32, sets the network read-timeout, where N is given in seconds.

       -tlog  toggles between using a Lynx Trace  Log  and  stderr  for  trace  output  from  the
              session.

       -tna   turns on "Textfields Need Activation" mode.

       -trace turns on Lynx trace mode.  Destination of trace output depends on -tlog.

       -trace_mask=value
              turn  on optional traces, which may result in very large trace files.  Logically OR
              the values to combine options:

              1  SGML character parsing states

              2  color-style

              4  TRST (table layout)

              8  configuration  (lynx.cfg,  .lynxrc,  .lynx-keymaps,   mime.types   and   mailcap
                 contents)

              16 binary string copy/append, used in form data construction.

              32 cookies

              64 character sets

              128
                 GridText parsing

              256
                 timing

       -traversal
              traverse  all  http links derived from startfile.  When used with -crawl, each link
              that begins with the same string as startfile is output to  a  file,  intended  for
              indexing.  See CRAWL.announce for more information.

       -trim_input_fields
              trim input text/textarea fields in forms.

       -underline_links
              toggles use of underline/bold attribute for links.

       -underscore
              toggles use of _underline_ format in dumps.

       -unique_urls
              check  for  duplicate  link numbers in each page and corresponding lists, and reuse
              the original link number.

       -use_mouse
              turn on mouse support, if available.  Clicking the left  mouse  button  on  a  link
              traverses it.  Clicking the right mouse button pops back.  Click on the top line to
              scroll up.  Click on the bottom line to scroll down.  The first  few  positions  in
              the  top  and  bottom  line may invoke additional functions.  Lynx must be compiled
              with ncurses or slang to support this feature.  If ncurses is  used,  clicking  the
              middle  mouse  button  pops  up a simple menu.  Mouse clicks may only work reliably
              while Lynx is idle waiting for input.

       -useragent=Name
              set alternate Lynx User-Agent header.

       -validate
              accept only http URLs (for validation).  Complete security  restrictions  also  are
              implemented.

       -verbose
              toggle [LINK], [IMAGE] and [INLINE] comments with filenames of these images.

       -version
              print version information, and exit.

       -vikeys
              enable vi-like key movement.

       -wdebug
              enable  Waterloo  tcp/ip packet debug (print to watt debugfile).  This applies only
              to DOS versions compiled with WATTCP or WATT-32.

       -width=NUMBER
              number of columns for formatting of dumps, default is 80.  This is limited  by  the
              number of columns that Lynx could display, typically 1024 (the MAX_LINE symbol).

       -with_backspaces
              emit backspaces in output if -dump'ing or -crawl'ing (like 'man' does)

       -xhtml_parsing
              tells  Lynx  that  it can ignore certain tags which have no content in an XHTML 1.0
              document.  For example "<p/>" will be discarded.

COMMANDS

       o  Use Up arrow and Down arrow to scroll through hypertext links.

       o  Right arrow or Return will follow a highlighted hypertext link.

       o  Left Arrow will retreat from a link.

       o  Type "H" or "?" for online help and descriptions of key-stroke commands.

       o  Type "K" for a complete list of the current key-stroke command mappings.

ENVIRONMENT

       In addition to various "standard" environment variables such as HOME, PATH, USER, DISPLAY,
       TMPDIR, etc, Lynx utilizes several Lynx-specific environment variables, if they exist.

       Others  may  be  created  or  modified by Lynx to pass data to an external program, or for
       other reasons.  These are listed separately below.

       See also the sections on SIMULATED CGI SUPPORT and NATIVE LANGUAGE SUPPORT, below.

       Note:  Not all environment variables apply to all types of platforms  supported  by  Lynx,
       though most do.  Feedback on platform dependencies is solicited.

       Environment Variables Used By Lynx:

       COLORTERM           If  set,  color  capability  for  the terminal is forced on at startup
                           time.  The actual value assigned to the  variable  is  ignored.   This
                           variable  is only meaningful if Lynx was built using the slang screen-
                           handling library.

       LYNX_CFG            This variable, if set, will override the default location and name  of
                           the global configuration file (normally, lynx.cfg) that was defined by
                           the  LYNX_CFG_FILE   constant   in   the   userdefs.h   file,   during
                           installation.  See the userdefs.h file for more information.

       LYNX_HELPFILE       If  set, this variable overrides the compiled-in URL and configuration
                           file URL for the Lynx help file.

       LYNX_LOCALEDIR      If set, this variable overrides the compiled-in location of the locale
                           directory which contains native language (NLS) message text.

       LYNX_LSS            This  variable,  if  set,  specifies  the location of the default Lynx
                           character style sheet file.  [Currently only meaningful  if  Lynx  was
                           built using experimental color style support.]

       LYNX_SAVE_SPACE     This variable, if set, will override the default path prefix for files
                           saved to disk that is defined in the lynx.cfg  SAVE_SPACE:  statement.
                           See the lynx.cfg file for more information.

       LYNX_TEMP_SPACE     This  variable,  if  set,  will  override  the default path prefix for
                           temporary files that was defined during installation, as well  as  any
                           value that may be assigned to the TMPDIR variable.

       MAIL                This  variable  specifies  the  default  inbox Lynx will check for new
                           mail, if such checking is enabled in the lynx.cfg file.

       NEWS_ORGANIZATION   This variable, if set, provides the string used in  the  Organization:
                           header  of  USENET news postings.  It will override the setting of the
                           ORGANIZATION environment variable, if it is also set  (and,  on  UNIX,
                           the contents of an /etc/organization file, if present).

       NNTPSERVER          If  set,  this variable specifies the default NNTP server that will be
                           used for USENET news reading and posting with Lynx, via news: URL's.

       ORGANIZATION        This variable, if set, provides the string used in  the  Organization:
                           header  of  USENET  news  postings.   On  UNIX,  it  will override the
                           contents of an /etc/organization file, if present.

       PROTOCOL_proxy      Lynx supports the use of  proxy  servers  that  can  act  as  firewall
                           gateways  and  caching  servers.   They  are  preferable  to the older
                           gateway servers (see WWW_access_GATEWAY, below).  Each  protocol  used
                           by Lynx, (http, ftp, gopher, etc), can be mapped separately by setting
                           environment  variables  of   the   form   PROTOCOL_proxy   (literally:
                           http_proxy,        ftp_proxy,       gopher_proxy,       etc),       to
                           "http://some.server.dom:port/".  See Lynx Users Guide  for  additional
                           details and examples.

       SSL_CERT_DIR        Set to the directory containing trusted certificates.

       SSL_CERT_FILE       Set   to  the  full  path  and  filename  for  your  file  of  trusted
                           certificates.

       WWW_access_GATEWAY  Lynx still supports use of gateway servers, with the servers specified
                           via  "WWW_access_GATEWAY"  variables (where "access" is lower case and
                           can be "http",  "ftp",  "gopher"  or  "wais"),  however  most  gateway
                           servers  have  been  discontinued.   Note  that  you  do not include a
                           terminal  '/'  for  gateways,  but  do  for   proxies   specified   by
                           PROTOCOL_proxy  environment  variables.   See  Lynx  Users  Guide  for
                           details.

       WWW_HOME            This variable, if set, will override the default startup URL specified
                           in any of the Lynx configuration files.

       Environment Variables Set or Modified By Lynx:

       LYNX_PRINT_DATE     This variable is set by the Lynx p(rint) function, to the Date: string
                           seen in the document's "Information about" page (= cmd), if  any.   It
                           is  created  for  use by an external program, as defined in a lynx.cfg
                           PRINTER: definition statement.  If the field does not  exist  for  the
                           document,  the  variable  is  set  to a null string under UNIX, or "No
                           Date" under VMS.

       LYNX_PRINT_LASTMOD  This variable is set by the Lynx p(rint) function, to  the  Last  Mod:
                           string  seen  in  the  document's "Information about" page (= cmd), if
                           any.  It is created for use by an external program, as  defined  in  a
                           lynx.cfg  PRINTER:  definition statement.  If the field does not exist
                           for the document, the variable is set to a null string under UNIX,  or
                           "No LastMod" under VMS.

       LYNX_PRINT_TITLE    This  variable  is  set by the Lynx p(rint) function, to the Linkname:
                           string seen in the document's "Information about"  page  (=  cmd),  if
                           any.   It  is  created for use by an external program, as defined in a
                           lynx.cfg PRINTER: definition statement.  If the field does  not  exist
                           for  the document, the variable is set to a null string under UNIX, or
                           "No Title" under VMS.

       LYNX_PRINT_URL      This variable is set by the Lynx p(rint) function, to the URL:  string
                           seen  in  the document's "Information about" page (= cmd), if any.  It
                           is created for use by an external program, as defined  in  a  lynx.cfg
                           PRINTER:  definition  statement.   If the field does not exist for the
                           document, the variable is set to a null string under UNIX, or "No URL"
                           under VMS.

       LYNX_TRACE          If set, causes Lynx to write a trace file as if the -trace option were
                           supplied.

       LYNX_TRACE_FILE     If set, overrides the compiled-in name of the  trace  file,  which  is
                           either  Lynx.trace  or  LY-TRACE.LOG (the latter on the DOS platform).
                           The trace file is in either case relative to the home directory.

       LYNX_VERSION        This variable is always set by Lynx, and may be used  by  an  external
                           program to determine if it was invoked by Lynx.  See also the comments
                           in the distribution's sample mailcap file, for notes on usage in  such
                           a file.

       TERM                Normally, this variable is used by Lynx to determine the terminal type
                           being used to invoke Lynx.  If, however, it is unset at  startup  time
                           (or  has  the value "unknown"), or if the -term command-line option is
                           used (see OPTIONS section above), Lynx will set or modify its value to
                           the user specified terminal type (for the Lynx execution environment).
                           Note: If set/modified by Lynx, the values of the LINES and/or  COLUMNS
                           environment variables may also be changed.

       If  built  with  the cgi-links option enabled, Lynx allows access to a cgi script directly
       without the need for an http daemon.

       When executing such "lynxcgi scripts" (if enabled), the following variables may be set for
       simulating a CGI environment:

       CONTENT_LENGTH

       CONTENT_TYPE

       DOCUMENT_ROOT

       HTTP_ACCEPT_CHARSET

       HTTP_ACCEPT_LANGUAGE

       HTTP_USER_AGENT

       PATH_INFO

       PATH_TRANSLATED

       QUERY_STRING

       REMOTE_ADDR

       REMOTE_HOST

       REQUEST_METHOD

       SERVER_SOFTWARE

       Other  environment variables are not inherited by the script, unless they are provided via
       a LYNXCGI_ENVIRONMENT statement in the configuration file.  See the lynx.cfg file, and the
       (draft)  CGI  1.1  Specification <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The CGI Specification, and other associated documentation, should be consulted for general
       information on CGI script programming.

NATIVE LANGUAGE SUPPORT

       If  configured  and  installed  with Native Language Support, Lynx will display status and
       other messages in your local language.  See the file ABOUT_NLS in the source distribution,
       or at your local GNU site, for more information about internationalization.

       The following environment variables may be used to alter default settings:

       LANG                This variable, if set, will override the default message language.  It
                           is an ISO 639 two-letter  code  identifying  the  language.   Language
                           codes are NOT the same as the country codes given in ISO 3166.

       LANGUAGE            This  variable,  if  set,  will override the default message language.
                           This is a GNU extension that  has  higher  priority  for  setting  the
                           message catalog than LANG or LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These  variables,  if  set,  specify  the  notion  of  native language
                           formatting style.  They are POSIXly correct.

       LINGUAS             This variable, if set prior to  configuration,  limits  the  installed
                           languages  to  specific  values.  It is a space-separated list of two-
                           letter codes.  Currently, it is hard-coded to a wish list.

       NLSPATH             This variable, if  set,  is  used  as  the  path  prefix  for  message
                           catalogs.

       Note that man page availability and section numbering is somewhat platform dependent,  and
       may vary from the above references.

       A  section  shown  as  (GNU), is intended to denote that the topic may be available via an
       info page, instead of a man page (i.e., try "info subject", rather than "man subject").

       A section shown as (?) denotes that documentation on the topic exists, but is not part  of
       an  established documentation retrieval system (see the distribution files associated with
       the topic, or contact your System Administrator for further information).

ACKNOWLEDGMENTS

       Lynx has incorporated code from a variety of sources along the way.  The earliest versions
       of  Lynx  included  code  from  Earl  Fogel  of  Computing  Services  at the University of
       Saskatchewan, who implemented HYPERREZ in the Unix environment.  HYPERREZ was developed by
       Niel  Larson  of  Think.com and served as the model for the early versions of Lynx.  Those
       versions also incorporated libraries  from  the  Unix  Gopher  clients  developed  at  the
       University  of  Minnesota,  and  the later versions of Lynx rely on the WWW client library
       code developed by Tim Berners-Lee and the WWW community.  Also a special thanks to  Foteos
       Macrides who ported much of Lynx to VMS and did or organized most of its development since
       the departures of Lou Montulli and Garrett Blythe from the University  of  Kansas  in  the
       summer  of  1994  through  the  release  of  v2.7.2,  and  to  everyone on the net who has
       contributed to Lynx's development  either  directly  (through  patches,  comments  or  bug
       reports) or indirectly (through inspiration and development of other systems).
