Well it makes a few use cases more complicated. You can't run WPKG from an 
USB Stick without some more cmd-wizardry because you don't know the path 
(specifically the drive letter) of your source. 

WPKG already has code in it to find wpkg_base. The only step left would be 
exporting this as an environment variable.

With WPKG_BASE defined and a common directory structure you could have 
relative directory paths in your definitions and your WPKG would be 
portable without fears that your custom cmd-fu might find a different 
basedir than wpkg thinks.

And maybe a complete CMD script less to worry about, which is always nice. 
:)
