2 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.

2 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.

-bibhost=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  or .lynxrc files.  Lynx tries the cfg-file
                 setting first.

-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.  The feature is normally
              available for curses configurations, but inactive.  To  activate
              it,  use  the  "|"  character  or  the  LINEWRAP_TOGGLE command.
              Toggling this option makes the feature altogether unavailable.

-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 when  -dump'ing  and  -crawl'ing,  mark
              wrapped lines of <pre> 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).

              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.

              present.

-justify
              do justification of text.

-link=NUMBER
              starting count for lnk#.dat files produced by -crawl.

              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
              prints  the  MIME  header  of  a fetched document along with its
              source.

              does  not disable any CCs which are incorporated within a mailto
              URL or form ACTION.

-nocolor
              force color mode off, overriding terminal capabilities  and  any
              -color flags, COLORTERM variable, and saved .lynxrc settings.

-noexec
              disable local program execution. (DEFAULT)

-nomore
              disable -more- string in statusline messages.

-nonrestarting_sigwinch
              This  flag  is  not  available  on all systems, Lynx needs to be
              compiled with HAVE_SIGACTION defined.  If available,  this  flag
              may  cause Lynx to react more immediately to window changes when
              run within an xterm.

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

-nopause
              disable forced pauses for statusline messages.

-noprint
              disable most print functions.

              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.

bookmark_exec
                 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 users.  Set to all restricted,  except
                 for:  inside_telnet, outside_telnet, inside_ftp, outside_ftp,
                 inside_rlogin,  outside_rlogin,  inside_news,   outside_news,
                 telnet_port, jump, mail, print, exec, and goto.  The settings
                 for these,  as  well  as  additional  goto  restrictions  for
                 specific  URL schemes that are also applied, are derived from
                 definitions within userdefs.h.

                 disallow access to, or creation of, hidden (dot) files.

download
                 disallow some downloaders in  the  download  menu  (does  not
                 imply disk_save restriction).

editor
                 disallow external editing.

exec
                 disable execution scripts.

exec_frozen
                 disallow the user from changing the local execution option.

                 disallow  some  "EXTERNAL" configuration lines if support for
                 passing  URLs  to  external  applications  (with  the  EXTERN
                 command) is compiled in.

file_url
                 disallow  using  G)oto,  served  links or bookmarks for file:
                 URLs.

goto
                 disable the `g' (goto) command.

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

-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.

2 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.

2 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.

2 Simulated Cgi Support
       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.

2 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).

2 Acknowledgments
       Lynx  has  incorporated  code  from a variety of sources along the way.
       The earliest versions of Lynx included code from Earl Fogel of  Comput-
       ing  Services at the University of Saskatchewan, who implemented HYPER-
       REZ 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 Uni-
       versity 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 indirect-
       ly (through inspiration and development of other systems).
