# tcsh.man2html, Dave Schweisguth <dcs@proton.chem.yale.edu>

|
|
# Notes:
|
|
#
|
|
# Always puts all files in the directory tcsh.html, creating it if necessary.
|
|
# tcsh.html/top.html is the entry point, and tcsh.html/index.html is a symlink
|
|
# to tcsh.html/top.html so one needn't specify a file at all if working through
|
|
# a typically configured server.
|
|
#
|
|
# Designed for tcsh manpage. Guaranteed not to work on manpages not written
|
|
# in the exact same style of nroff -man, i.e. any other manpage.
|
|
#
|
|
# Makes links FROM items which are both a) in particular sections (see
|
|
# Configuration) and b) marked with .B or .I. Makes links TO items which
|
|
# are marked with \fB ... \fR or \fI ... \fR.
|
|
#
|
|
# Designed with X Mosaic in mind and tested lightly with lynx. I've punted on
|
|
# HTML's lack of a .PD equivalent and lynx's different <menu> handling.
|
|
|
|
# Emulate #!/usr/local/bin/perl on systems without #!

Usage: $whatami [-1icsu] [-C dir] [-d dir] [-h host] [file]

Without [file], reads from tcsh.man or stdin.
|
|
-1 Makes a single page instead of a table of contents and sections
|
|
-i Makes a CGI searchable index script, tcsh.html/tcsh.cgi, intended
|
|
for a server which respects the .cgi extension in any directory.
|
|
-c Like -i, but the CGI script is intended for a server which wants
|
|
scripts in /cgi-bin (or some other privileged directory separate
|
|
from the rest of the HTML) and must be moved there by hand.
|
|
-C dir Uses /dir instead of /cgi-bin as the CGI bin dir.
|
|
Meaningless without -c.
|
|
-d dir Uses /dir/tcsh.html instead of /tcsh.html as the HTML dir.
|
|
Meaningless without -c.
|
|
-D dir Uses /dir.html instead of /tcsh.html as the HTML dir.
|
|
Meaningless without -c.
|
|
-G name Uses name instead of tcsh.cgi as the name of the CGI script.
|
|
Meaningless without -c or -i.
|
|
-h host Uses host as the host:port part of the URL to the entry point.
|
|
Meaningless without -c.
|
|
-s Filenames are shorter (max 8 + 3) but less descriptive.

<H2>The <I>tcsh</I> mailing lists</H2>
|

There are three <I>tcsh</I> mailing lists:
|
|
<DL>
|
|
<DT>
|
|
<I>tcsh@mx.gw.com</I>
|
|
<DD>
|
|
The <I>tcsh</I> maintainers and testers' mailing list.
|
|
<DT>
|
|
<I>tcsh-diffs@mx.gw.com</I>
|
|
<DD>
|
|
The same as <I>tcsh@mx.gw.com</I>, plus diffs for each new
|
|
patchlevel of <I>tcsh</I>.
|
|
<DT>
|
|
<I>tcsh-bugs@mx.gw.com</I>
|
|
<DD>
|
|
Bug reports.
|
|
</DL>
|
|
You can subscribe to any of these lists by sending mail to
|
|
<I><A HREF="mailto:listserv@mx.gw.com">listserv@mx.gw.com</A></I> with the
|
|
text "subscribe <list name> <your name>" on a line by
|
|
itself in the body. <list name> is the name of the mailing list,
|
|
without "@mx.gw.com", and <your name> is your real name, not your
|
|
email address. You can also ask the list server for help by sending
|
|
only the word "help".
