# bunch v1.0 ... a Bourne Shell Script program for UNIX... made to fit
# almost any UNIX-style architecture including LINUX, 386BSD, ULTRIX, etc etc
#
#
# I put no burdons of copyright on this (how could I? :) )...I only ask that
# you give me a little note of thanks if this is actually helpful to you.
#
# I have ultra-commented this program for one main reason: I like for beginners
# to alter it just as much as me. :) Since I'm only a beginner in shell script
# coding myself, it may be totally useless :) but here's what it does anyways.
#
# Oftentimes I want to edit the IDEAS, BUGS or TYPOS files in the
# circle/lib/text portion of the Circle2.0 code... but you can't do that
# directly while the MUD is running or you'll run into file-sharing violations
# that could keep any modifications you make(line deletions etc) from going
# through. SO...I made this little program.
#
# say you have two files for ideas... ideas.old and ideas. You can't modify
# ideas conveniently while the MUD is running for the above reasons...so
# you use bunch to put these two files together and reset the ideas file.
# example:
# files: ideas ideas.old ...you want to make a file called ideas.fix that has
# the info from BOTH files.
# you COULD do it the 3-line way, which isn't too hard...but it's quite time
# consuming...and there's the chance for a messup :) here, there isn't.
# bunch -i ideas old fix
# bunch will concatenate ideas and ideas.old, and put it in the file ideas.fix
# it will also make sure that you aren't trying to put ideas.old and ideas
# in ideas.old...because that causes major problems.
# it also won't run if ideas is already empty...this indicates that the file
# bunch has already been run OR that it doesn't need to be run. :)
#
# You can, of course, cut all of this commenting out as it's really unneeded :)
# this is a VERY simple program but it has made MY life much easier. :)
# i've tried to idiotproof as much of it as I can but there are things I'm
# sure to have missed...so find them for me! :) Thanks.
#
# BTW: YES, I know I could have chosen to allow this to work for any file VERY
# easily (perhaps easier than this)...but I think this is an easier and faster
# way for the user. You can see how I add switches...just add ones of your own
# if'n ya wanna :)
