He is not a trained programmer. I have not seen some of the other
programs he has written. I'm usually pretty critical of inefficient
code. One thing I do in nearly all of my scripts is to set up variables
for commants, such as:
RM=/bin/rm
I also set up a prefix, or path to where my script is run from. So,
let's say my code is in /foo/bin, but there is a symlink in
/usr/local/bin. I set up the prefix so that it resolves the symlink so
when I source other files, I get them from the exact same place. This is
simple in BASH, but a bit tricky in tcl.
