LYNX-DEV LYNX.RNH

[Brian Tillman, x8425]

If anyone's interested in a Runoff version of LYNX.HLP, here's LYNX.RNH.  
Personally, I do all my help files with Runoff because I think they look better.

NAME
 lynx - a general purpose distributed information browser for the World 
Wide Web
.left margin 0
2 SYNOPSIS
.left margin 4
 Lynx [options] [path or URL]
.left margin 2
 use "lynx -help" to display a complete list of current options.

2 DESCRIPTION
.left margin 2
 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.

2 OPTIONS
.left margin 2
 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."
.left margin 3

.left margin 8
If the only argument is '-', then Lynx expects to receive
the arguments from stdin. 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).

2 ACKNOWLEDGMENTS
.left margin 2
 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 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
University of Kansas in the summer of 1994 through the current release
of v2.7.1, 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).
