Simple unshar script

[Tom Neff]

More source in our Stamp Out Chatter campaign.  I use this as something
to pipe 'rn' shar articles into.  There are fancier things with perl
and custom programs, but I either don't have them or can't understand
them :-)

#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create:
#	unshar
# This archive created: Mon Jul 10 14:07:01 1989

X#	This script uses sed(1) and sh(1) to unpack a shell archive from
X#	the standard input or a file argument.  Results are written to
X#	the current directory unless you supply a directory name as the
X#	first argument.
X
X#	Usage:  unshar [ <filename>|<dirname> ]
X
X#	Since unshar can be a filter, it's nice with rn or mailers.
