Linux 2.6 - man page for www-browser (linux section 1)

LYNX(1) 										  LYNX(1)

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

       lynx [options] [path or URL]

       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  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.

       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.,
       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.

	      apply restrictions for anonymous account, see also -restrictions.

	      charset for documents that don't 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 switch.

       -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 10.

       -case  enable case-sensitive string searching.

	      Toggle center alignment in HTML TABLE.

	      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

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

	      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 immediately.

		 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

       -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

	      separate incremental display stages with MessageSecs delay

       -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 in <pre> when -dump'ing and -crawl'ing, mark wrapped lines
	      in interactive session.

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

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

	      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 session.

	      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.

	      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 '---'.

       -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 behavior.

		 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 present.

	      do justification of text.

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

	      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 configuration.

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

	      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

	      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 switch.

       -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 '---'.

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

	      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 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

	      documents they returned are sought with the PREV_DOC command or  from  the  History

	      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

	      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

	      can be changed in userdefs.h or lynx.cfg.  The  command  line  switch  toggles  the

	      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.

	      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

	      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 seconds.

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

       -tna   turns on "Textfields Need Activation" mode.

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

	      turn  on optional traces, which may result in very large trace files.  Logically OR

	      32 cookies

	      64 character sets

		 GridText parsing


	      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 text/textarea fields in forms.

	      toggles use of underline/bold attribute for links.

	      toggles use of _underline_ format in dumps.

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

	      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.

	      set alternate Lynx User-Agent header.

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

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

	      print version information, and exit.

	      enable vi-like key movement.

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

	      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).

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

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

       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.

       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

       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

       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

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

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

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

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

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














       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 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

       This is the Lynx v2.8.7 Release; development is in progress for 2.8.8.

       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 in-
       fo 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).

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