My first shell script

[Gerard Samuel]

Well I had just installed mhonarc to turn a mailling list archive into 
html, and didn't know how to make the
process automagic.
I never wrote a shell script from scratch before, and came up with this 
after a brief search on Google for commands.
It does work, but Im just looking for critical comments to the script, 
to see if I can improve on it..
If not, its in the archive for others to use it.
Thanks
