There is a reason for this.  UUENCODE does not compress, as a matter of fact,
it increases the file size quite significantly, converting binary codes to 
ASCII so they can be mailed.

You can find it on Fish 40, but unfortunately that is Arc.16 and they are
up to about Arc.23.  Everyone should really have Arc.  It is a standard
in the IBM world for compressing multiple files, and has moved into the
Amiga and ST worlds as well.  The Arc.23 is supposed to have much better
compression choice.

I was going to do this, but the Arc file of JTime has about 5 or 6 files
in it, and I didn't feel like uploading each one, uudecoding all the 
binaries, and then sharring the thing.  One upload of the Arc and I was
done.  

I am sure the Arc posting was shorter then the equivalent shar posting would
have been...

[I feel so much better now, ahhhh.....]
