This is MRBackup, version 1.3. This program was written under Manx
Aztec C, version 3.40a, to run under KickStart 1.2. The source was
written with 4 character tab settings, using Z, a vi-like editor
packaged with the Aztec C compiler. If you would like a
copy of my file retab utility to remove or alter the tabs, just ask.
Also, if you did not receive source with this distribution, it is
available for the asking.
Be sure to rename the file MRBackup.INI to MRBackup.INIT and copy it
to the S: directory.

About the code...(entering excuse/apology mode)
MRBackup evolved from a simple-minded program with a tty-style interface
to the version you see here. Though I'm a true believer in structured
programming techniques, good design and consistent style, you might not
see a lot of that in this program. In fact, the code is quite "hacky".
I also am a true believer in "using someone else's wheel" (if it's free)
rather than inventing my own. I've incorporated several public domain
sources into MRBackup, each having its own particular style. I've made
every effort to give credit where credit is due. If I've slighted anyone,
please help me to correct the problem. This project was also a learning
experience in that I had not attempted any Intuition-based programming
prior to this effort. I've made all of the dumb mistakes that one makes
with Intuition (I still have a problem with mutual exclusion and extended
selection) but I have a better grasp on it now. I may change the user
interface at a later date to use a more gadget-driven approach. I sure
wish Aztec would give us function prototypes! Better yet, I wish THINK
Technologies would give us a LightSpeed C for the Amiga.
There is nothing particularly clever about any of the disk-related stuff.
I've adhered to vanilla AmigaDOS throughout. I'm sure there are much
faster techniques for moving data to/from floppies. I don't have the
time to investigate them. This program is also incapable of archiving
a single file which is larger than a floppy disk. Someone else will
probably have to tackle that (or wait a loooong time).
Though I've had my Amiga since October '86, I've been working on the
internals of a rather dry, heavily algorithmic program for which the user
interface is currently the least of my worries. MRBackup was a fun
diversion from that, but now I've got to get back to work. Please feel
free to modify this program and re-release it. If you make substantial
changes, I'd like to hear about them. I'd also like you to change the
name of the program, perhaps to <your initials>Backup, as I've done.
Funny how many people call it "Mister Backup"...
At 37 years of age, I'm still going through an upheaval in terms of
personal style. If you look closely, you'll see things like part1_part2
giving way to part1Part2, an influence of working on a MacIntosh during
the day and (obviously) a convention I've grown to like. If I were a
little more vain, I might have gone through the source, performing
global search and replace on everything. If I were getting paid for it...
'Nuff yak. I've received enough inquiries about the source to know that
there's a need for this sort of thing, even if mine isn't the be-all and
end-all. I hope this helps you get to where you want to be.
