Wow.

A) why not just "tar -cJf" it and attach using MIME.
B) if you have to roll your own, wny not use "shar"?
    it just does all that stuff for you.
C) you can use compression options with shar, too,
    to make it much moore compact than just "uuencoding"
    all the files
D) *plus* if files meet the criteria for "text" files,
    the uuencoding step can be skipped.

So, what are you really trying to accomplish?
