init.d script for folding at home client

[Jason Pepas <j.pepas@mail.utexas.edu>]

hey guys,

I decided to donate my spare cpu cycles with the folding at home linux client.

So, I wanted to try and to this the "proper way", ie, with a init.d script.  I 
started from /etc/init.d/skeleton and came up with this (see below).

I put the client in /usr/local/folding, and made the entire dir chown nobody, 
then update-rc.d folding.sh defaults.

It works fine, but can anyone give me some criticism on this, specifically 
security aspects?  This is my first time to do this kind of thing.

here is /etc/init.d/folding.sh: (the line wraps are a little fubared)
