A couple of weeks ago I saw someone who wanted to be able to do a "finger"
under a gopher server.  To this person (whose name escapes me) and to
anyone else that ever wanted to finger people via a gopher, this bud's
for you...

I hacked this together in about 2 or 3 hours, so I cannot guarentee
that it's bulletproof.  But, it does seem to work.  If you use it, send
me some mail -- I'd love to see it in action! :-)

It requires that you have perl, which you can get from many places.  Instructions
for use are at the top of the program.  Go nuts.

# This program uses inetd to get started, so..  you'll need a line in
# your inetd.conf something like the following:
#
# gophinger stream tcp nowait tcp /usr/local/bin/gophinger.perl gophinger
#
# and a line in your /etc/services file something like:
#
# gophinger	71/tcp
#
# in your .Links file, try something to the effect of:
#
# Type=1
# Name=Gophinger finger service
# Host=yourhost.what.ever.that.is
# Port=71
# Path=+
#
# I've structured it so that you can get the list of names in whatever
# way you want.  Gophinger expects to use an /etc/passwd like file.
# You can either use /etc/passwd, or use a modified version of the file.
# for instance, you can create a file like:
# 
# sbalneav@silver.cs.umanitoba.ca::::Scott L. Balneaves::
# sbalneav@ccu.Umanitoba.ca::::Scott L. Balneaves::
#
# as a test, and have gophinger go after that.  That way you can finger
# people on different hosts (internet coke machines, etc :-)
#
# You can also use YP (or NIS if you like) to get the info, pass it
# through a filter that removes certain names, etc.  Whatever you like,
# so long as the output looks like a passwd entry, you'll be fine.
#
# At any rate, $command is the command to use to get the passwd-like file
# into gophinger. I've included a couple, commented out, and one which
# is guarenteed to work :-) (note the trailing pipe symbol at the end of
# the command string)
#
# This program was a quick hack, so don't expect perfection.
