Re: Setting target execution order

[Noel Yap]

Sorry, I tried going through this "stripped down" version but I just don't have 
the time to cut through the extraneous stuff.  Can you supply a /really/ 
stripped down version and provide explanations as to why creating prereq's for 
the target "gzip" won't
work in your situation?

Thanks,
Noel
