Description
-----------
nomarch lists/extracts/tests `.arc' archives. (It also handles `.ark'
files, they're exactly the same.) This is a *very* outdated file
format which should never be used for anything new, but unfortunately,
you can still run into it every so often (especially if you mess about
with old CP/M stuff). So nomarch is handy as a way to deal with these
files.
For more on how nomarch works and how to use it, do `man nomarch' once
it's installed.
Installation
------------
Check the Makefile is ok (it should be), then do `make' and (as root)
`make install'.
Why not just use `arc'?
-----------------------
`arc' is non-Free. For a while this didn't annoy me that much, and I
put up with using it because there wasn't really anything else I could
use. But once I realised that I could probably write my own extraction
program, and that some old .arc files aren't likely to go away (for
example, the Walnut Creek CP/M CD-ROM contains well over a thousand),
I thought I'd try writing something a bit more useful than a picture
viewer for once. :-)
Why the name?
-------------
Since there are at least two different programs called `unarc' already
(one is an old CP/M program, the other isn't .arc-related), I had to
pick something a bit more obscure. I considered `arcbgon', but I
thought that was a little tacky. :-) When I noticed that there was a
word looking so similar to `no more arc', I went with that instead,
even if the mundane meaning is a little, uh, grandiose...
(Though it looks like it might also be Spanish for `filename' or
something, which could be a bit weird. Oh well.)
What about Unisys?
------------------
nomarch is capable of reading LZW-compressed files, so it has the same
legal status as a GIF decoder. Even in their current
set-lawyers-to-kill state, I don't think Unisys have a problem with
programs which only *read* LZW. Their patent expires soon anyway, and
once that happens we can all just point at them and laugh. I know I
will. :-)
