       lynx  - a general purpose distributed information browser for the World
       Wide Web

       lynx [options] [optional	paths or URLs]

       lynx [options] [path or URL] -get_data

       lynx [options] [path or URL] -post_data

       Use "lynx -help"	to display a complete list of current options.

       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

       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.

       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  shown  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.,


       Lynx recognizes "1", "+", "on" and "true" for  true  values,  and  "0",
       "-",  "off"  and	 "false"  for  false  values.  Other option-values are

       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.

	      apply    restrictions    for   anonymous	 account,   see	  also

	      charset for documents that do not	specify	it.

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

	      use this instead of unrecognized charsets.

	      set  authorization  ID  and  password for	protected documents at
	      startup.	Be sure	to protect any script  files  which  use  this

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

	      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.

	      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.

	      set the NUMBER of	documents cached in memory.   The  default  is

       -case  enable case-sensitive string searching.

	      toggles  center  alignment  in HTML TABLE.  Normally table cells
	      are centered on the table	grid.  Set this	option "on" to disable
	      centering.  The default is "off".

	      specifies	 a  Lynx  configuration	 file  other  than the default

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

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

	      write  keystroke	commands  and  related	information   to   the
	      specified	file.

	      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:

		 causes	  the	script	to  stop,  and	forces	Lynx  to  exit

		 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.

		 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.

	      toggles collapsing of BR tags.

       -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.

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

	      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.

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

	      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.

	      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.

	      separate incremental display stages with MessageSecs delay

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

       -delay add DebugSecs delay after	each progress-message

	      set the display variable for X rexec-ed programs.

	      set the charset for the terminal output.

	      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

	      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.

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

	      enable emacs-like	key movement.

	      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).

	      include all versions of files in local VMS directory listings.

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

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

	      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

	      Lynx recognizes these file suffixes as HTML:

		  ".sht", and

	      toggles forcing of the secure flag for SSL cookies.

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

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

	      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-

       -head  send a HEAD request for the mime headers.

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

	      control the display of hidden links.

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

		 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

		 hidden	links do not appear even in listings.

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

	      set homepage separate from start page.

	      toggles inclusion	of links for all images.

	      set the default index file to the	specified URL.

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

	      do justification of text.

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

	      for -dump, show URL-encoded links	decoded.

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

	      for -dump, show only the list of links.

	      disable URLs that	point to remote	hosts.

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

	      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

	      prints the MIME header of	a  fetched  document  along  with  its

	      toggles minimal versus valid comment parsing.

	      toggles nested-tables logic (for debugging).

	      number of	articles in chunked news listings.

	      maximum news articles in listings	before chunking.

	      disable bold video-attribute.

	      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.

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

	      disable local program execution.	(DEFAULT)

	      disable transmissions of Referer headers for file	URLs.

	      disable the link list feature in dumps.

       -nolog disable mailing of error messages	to document owners.

	      disable left/right margins in the	default	style sheet.

	      disable -more- string in statusline messages.

	      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.

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

	      disable forced pauses for	statusline messages.

	      disable most print functions.

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

	      disable transmissions of Referer headers.

	      disable reverse video-attribute.

	      disable SOCKS proxy usage	by a SOCKSified	Lynx.

	      disable the retrieval status messages.

	      disable title and	blank line from	top of page.

	      disable underline	video-attribute.

	      force numbering of links as well as form input fields

	      force numbering of links.

	      toggles display partial pages while loading.

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

	      toggles passive ftp connections.

	      set authorization	ID and password	for a protected	 proxy	server
	      at  startup.  Be sure to protect any script files	which use this

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

	      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-

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

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

       -print enable print functions.  (default)

	      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.

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

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

	      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.

		 restricts all options listed below.

		 disallow changing the location	of the bookmark	file.

		 disallow execution links via the bookmark file.

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

		 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 local	file management.

		 disallow saving to disk in the	download and print menus.

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

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

		 disallow external editing.

		 disable execution scripts.

		 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.

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

		 disable the "g" (goto)	command.

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

		 disallow  USENET  news	 posting for people coming from	inside
		 your domain (utmp required for	selectivity).

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

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

		 disable the "j" (jump)	command.

		 disallow multiple bookmarks.

		 disallow mail.

		 disallow USENET News posting.

		 disallow saving options in .lynxrc.

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

		 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.

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

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

		 disallow most print options.

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

		 disallow Unix Control-Z suspends with escape to shell.

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

		 disallow modifications	of the User-Agent header.

	      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.

	      disable recognition of rlogin commands.

	      toggles showing scrollbar.

	      toggles showing arrows at	ends of	the scrollbar.

	      require .www_browsable files to browse directories.

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

	      resumes session from specified file.

	      saves session to specified file.

	      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.

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

	      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.

	      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.

	      (Via which)  SOCKS5  proxy  to  connect:	any  network  traffic,
	      including	 all  DNS resolutions but the one for URL itself, will
	      be redirected through the	SOCKS5 proxy.  URL  may	 be  given  as
	      "", "", "", or
	      "" (and  IPv6  notation  if  so  supported).   A
	      SOCKS5  proxy may	also be	specified via the environment variable
	      SOCKS5_PROXY.  This option controls the builtin SOCKS5  support,
	      which is unrelated to the	option -nosocks.

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

	      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

	      disable SIGINT cleanup handler

	      allow non-http startfile and homepage with -validate.

	      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).

	      information for syslog call.

	      log requested URLs with syslog.

	      initialize parser, using Tag Soup	DTD rather than	SortaSGML.

	      disable recognition of telnet commands.

	      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.)

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

       -tlog  toggles  between	using  a  Lynx	Trace Log and stderr for trace

       More  than  one key can be mapped to a given command.  Here are some of
       the most	useful:

       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 or "u" will retreat from a link.

       o   Type	"H", "?", or F1	for online help	and descriptions of key-stroke

       o   Type	 "k"  or  "K"  for  a  list  of	the current key-stroke command

	   If the same command is mapped to the	same letter differing only  by
	   upper/lowercase only	the lowercase mapping is shown.

       o   Type	Delete to view history list.

       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

       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.
			   Protocols are indicated in a	URI by the name	before
			   ":",	e.g., "http" in	"http://some.server.dom:port/"
			   for HTML.

			   Depending  on   your	  system   configuration   and
			   supported   protocols,  the	environment  variables
			   recognized by lynx may include


			   See Lynx Users Guide	 for  additional  details  and

       SOCKS5_PROXY	   Is  inspected  if  -socks5_proxy  has not been used
			   (for	the same content).

       SSL_CERT_DIR	   Set	 to   the   directory	 containing    trusted

       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

       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:














       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.

       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

       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

       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).

       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  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).
