I found out how to use uud by reading the source code. I had the same problems
with the recent ckermit posts. It turns out that uue will break a large (>100K??)
file into smaller parts. This was done with the ckermit ARC file. I found out that
the first file includes the second, the second file includes the third file, and
so on until you get to the last file.

With the ckermit posts the files should be named:

ckermit1.uue  (or anything)
kerm_exe.uab
kerm_exe.uac
kerm_exe.uad
kerm_exe.uae

This is because uue named the files this when it split them. My problem was that I 
renamed them when I saved them from the USENET newsgroup. It wasn't until after I
read the source code to uue/uud that I discovered how to rename the files to 
rebuild the original KERM_EXE.ARC file from its components.

I haven't tried to decode the metafont files yets, but they must work the same
way. By the way, I don't believe that the UNIX uuencode/uudecode splits large files
into smaller files the way the DUMAS uue/uue programs do. 

About the ARC program. ARC521 has a bug which causes it to create ARCed files larged
then the sum of the individual files in some cases. This has been witnessed extensively
with the ST version of ARC521. The authoer of ARC521 denies that this problem exists,
but it can be replicated with certain files.

So, I don't want to upload the source code to ARC521 unless the author fixes that bug
first.
