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

  Lynx [options] [path or URL]

  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 PCs or Macs, or any other "curses-oriented"
  display).  It	will display hypertext markup language (HTML) documents	con-
  taining 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 and VMS.

  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 the only argument is '-', then Lynx expects to receive the argu-
       ments from stdin. This is to allow for the potentially very long	com-
       mand line that can be associated	with the -get_data or -post_data
       arguments (see below).

       used to specify the anonymous account.

       set authorization ID and	password for protected documents at startup.

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

       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.

       enable case-sensitive string searching.

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

       exit on left-arrow in startfile,	and disable save to disk.

       toggles handling	of Set-Cookie headers.

       with -traversal,	output each page to a file.  with -dump, format	out-
       put as with -traversal, but to stdout.

       set the display variable	for X rexec-ed programs.

       dumps the formatted output of the default document or one specified on
       the command line	to standard out. This can be used in the following
       way: lynx -dump http://www.crl.com/~subir/lynx.html.

       enable edit mode	using the specified EDITOR. (vi, ed, emacs, etc.)

       enable emacs-like key movement.

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

       define a	file where Lynx	will report HTTP access	codes.

       include all versions of files in	local VMS directory listings.

       forces the first	document to be interpreted as HTML.

  -ftp disable ftp access.

       send form data from stdin using GET method and dump results.

       send a HEAD request for the mime	headers.

       print this Lynx command syntax usage message.

       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.

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

       disable URLs that point to remote hosts.

       disable the link	list feature in	dumps.

       disable mailing of error	messages to document owners.

       disable forced pauses for statusline messages.

       disable print functions.

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

       disable transmissions of	Referer	headers.

       disable SOCKS proxy usage by a SOCKSified Lynx.

       disable the retrieval status messages.

       force numbering of links.

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

       send form data from stdin using POST method and dump results.

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

       restricts access	to URLs	in the starting	realm.

       flushes the cache on a proxy server (only the first document

       Lynx process.)

       turns on	WWW trace mode.

       traverse	all http links derived from startfile.	When used with
       -crawl, each link that begins with the same string as startfile is

       tions also are implemented.

       print version information.

  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.

  This is the Lynx v2.7	Release	for Unix/VMS

  Lynx has incorporated	code from a variety of sources along the way.  The
  earliest versions of Lynx included code from Earl Fogel of Computing Ser-
  vices	at the University of Saskatchewan, who implemented HYPERREZ in the
  Unix environment.  HYPERREZ was developed by Niel Larson of Think.com	and
  served as the	model for the early versions of	Lynx.  Those versions also
  incorporated libraries from the Unix Gopher clients developed	at the
  University of	Minnesota, and the later versions of Lynx rely on the WWW
  client library code developed	by Tim Berners-Lee and the WWW community.
  Also a special thanks	to Foteos Macrides who ported much of Lynx to VMS and
  did or organized most	of its development since the departures	of Lou Mon-
  tulli	and Garrett Blythe from	the University of Kansas in the	summer of
  1994 through the current release of v2.7, and	to everyone on the net who
  has contributed to Lynx's development	either directly	(through patches,
  comments or bug reports) or indirectly (through inspiration and development
  of other systems).
