# Make a shar file, keeping file sizes below a maximum, but as large as
# possible.  The output files are put in file01.shar through filenn.shar,
# where "file" is the output base name (default "prog").
# If one of the output files is named "README", it is placed first in the
# first shar file.
# Usage:
#	makeshar [-f n] [-n] [-m max-size] [-o output-base ] [shar-switches] file-list
# $Log: makeshar,v $
# Revision 1.7  1994/01/25  07:11:57  geoff
# Get rid of all old RCS log lines in preparation for the 3.1 release.
