Attempt at writing bdist_dpkg

[amk]

[This is a repeat of a note sent to the distutils-sig.  This list
 seems like a better place for discussing bdist_dpkg.]
 
I've found myself making a lot of Debian packages for various Python modules,
so I've started working on a bdist_dpkg.py module for Distutils.  Currently 
it's in nondist/sandbox/Lib/ in the Python CVS; you can download
a copy from
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/python/python/nondist/sandbox/Lib/bdist_dpkg.py
