Subject: uucat - updated version
Date: 29 Sep 90 07:35:26 GMT

I'm glad my program uucat.c was appreciated, and is used by
many of you out there.  So I decided to post an updated version.
For those who don't know what uucat is, here's a description:

You use it to uudecode multi-part uuencoded files.  It has worked
for all newsgroups I have tested so far.  It saves you the effort
of having to edit the files.  To compile it, extract everything
between the two lines which say 'CUT HERE', and save it as uucat.c.
To compile it on a Unix machine, type

> cc -o uucat uucat.c

On other machines, the C compiler is called something else.

In order to decode files, type

> uucat file1 file2 ... filen | uudecode
or

> cat file1 file2 ... filen | uucat | uudecode

or, if you already have concatenated them into one file

> uucat file | uudecode

Uucat is placed in the public domain, and I assume no responsibility
for its usage.

I would like to add the fact that some news readers have this function
built-in.. nn has, but rn, which I use, hasn't.
