exe cmd line --clean?

[Bob Davis]

I know I can use --clean when I build the exe with pp but I would like 
to have an option on the exe to conditionally do a clean.
For example a user is having a problem and I want to make sure all of 
the older versions of the unpacked stuff is cleaned and reinstalled.
I suppose I would have to make a call from the perl program and this 
seems problematic since I am currently running it when I am in my perl 
script.
