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/XP/7/8 or any POSIX
       platform,  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/XP/7/8, DOS DJGPP and
       OS/2.

       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.

       -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

       -default-colors
	      toggles  the default-colors feature which is normally set in the
	      lynx.cfg file.

       -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

	      Files specified on the command line are  formatted  as  HTML  if
	      their  names  end	 with one of the standard web suffixes such as
	      “.htm” or “.html”.  Use the -force_html option to	 format	 files
	      whose names do not follow this convention.

       -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.

	      This is most useful  when	 processing  files  specified  on  the
	      command line which have an unrecognized suffix (or the suffix is
	      associated with a non-HTML type, such as “.txt” for  plain  text
	      files).

	      Lynx recognizes these file suffixes as HTML:
	      “.ht3”,  “.htm”,	“.html3”,  “.html”, “.htmlx”, “.php3”, “.php”,
	      “.phtml”, “.sht”, and “.shtml”.

	      The -force_html option does not apply to non-interactive options
	      such as -dump or -crawl.

       -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 '---'.

	      Lynx  issues  an	HTTP  GET, sending the form to the path or URL
	      given on the command-line and prints the response of the server.
	      If  no  path  or URL is given, Lynx sends the form to the start-
	      page.

       -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.

       -image_links
	      toggles inclusion of links for all images.

       -index=URL
	      set the default index file to the specified URL.

       -ismap toggles  inclusion  of  ISMAP  links  when  client-side MAPs are
	      present.

       -justify
	      do justification of text.

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

       -list_inline
	      for -dump, show the links inline with the text.

       -listonly
	      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.

       -minimal
	      toggles minimal versus valid comment parsing.

       -nested_tables

       -nobrowse
	      disable directory browsing.

       -nocc  disable Cc: prompts for self copies of mailings.	Note that this
	      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)

       -nofilereferer
	      disable transmissions of Referer headers for file URLs.

       -nolist
	      disable the link list feature in dumps.

       -nolog disable mailing of error messages to document owners.

       -nomargins
	      disable left/right margins in the default style sheet.

       -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.

       -noredir
	      prevents automatic redirection and prints a message with a  link
	      to the new URL.

       -noreferer
	      disable transmissions of Referer headers.

       -noreverse
	      disable reverse video-attribute.

       -nosocks
	      disable SOCKS proxy usage by a SOCKSified Lynx.

       -nostatus
	      disable the retrieval status messages.

       -notitle

       -partial_thres=NUMBER
	      number  of  lines	 to  render  before  repainting	 display  with
	      partial-display logic

       -passive-ftp
	      toggles passive ftp connections.

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

       -popup toggles handling	of  single-choice  SELECT  options  via	 popup
	      windows or as lists of radio buttons.

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

	      Lynx  issues  an	HTTP POST, sending the form to the path or URL
	      given on the command-line and prints the response of the server.
	      If  no  path  or URL is given, Lynx sends the form to the start-
	      page.

       -preparsed
	      show HTML	 source	 preparsed  and	 reformatted  when  used  with
	      -source or in source view.

       -prettysrc
	      show HTML source view with lexical elements and tags in color.

       -pseudo_inlines
	      toggles pseudo-ALTs for inline images with no ALT string.

       -raw   toggles  default	setting of 8-bit character translations or CJK
	      mode for the startup character set.

       -realm restricts access to URLs in the starting realm.

       -read_timeout=N
	      Sets the read-timeout, where N is given in seconds.

       -reload
	      flushes the cache on a proxy server  (only  the  first  document
	      given on the command-line is affected).

       -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.

	      bookmark_exec
		 disallow execution links via the bookmark file.

	      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

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

	      outside_telnet
		 disallow telnets for people coming from outside  your	domain
		 (utmp required for selectivity).

	      print
		 disallow most print options.

	      shell
		 disallow shell escapes and lynxexec or lynxprog G)oto's.

	      suspend
		 disallow Unix Control-Z suspends with escape to shell.

	      telnet_port
		 disallow specifying a port in telnet G)oto's.

	      useragent
		 disallow modifications of the User-Agent header.

       -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_CFG_PATH	   If  set,  this  variable  overrides the compiled-in
			   search-list	of  directories	 used  to   find   the
			   configuration  files,  e.g., lynx.cfg and lynx.lss.
			   The list is delimited with ":" (or ";" for Windows)
			   like the PATH environment variable.

       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
			   curses 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/Windows platforms).  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.

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.

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 plat‐
       form 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 sub‐
       ject”, 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 Sys‐
       tem 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 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).
