Most of the scripts (notably the main 'poplog' script) were written in 
csh, if I remember.

I thought about it, but in the unlikely event that someone has a weird 
set-up with different .so.6 and .so files, poplog would still be happy.  
Besides that, I don't know an easy way of getting a bash script to check 
the destination of a symlink :)

True.  I'll make the change now.

popcd.tar is a tarball of gzipped tarballs, containing everything you need 
(and a few extras), except linux(motif)1553.tar.gz.  Since everything 
inside it is gzipped, there's not much point in gzipping it again.

That said, is it possible to provide some bzip2'ed versions of these 
files?  It provides marginally better compression than gzip, which would 
at least slice some time off downloads.
