Unfortunately, the distutils don't currently have a way to specify 
these.  I think we'll need to use only the ones that are distutils 
install targets at first, but of course the format is extensible.

OTOH, one supposed that at least the 'data_files' setup argument 
could be enhanced to allow a data type flag, that would then be used 
as a prefix name for those files, with a fallback to the DATA prefix 
if there isn't one specified.  But that's something that will require 
tagging support in the install_data command.  As it is, refactoring 
the distutils to track prefixes for the RECORD file is probably going 
to be...  challenging.  ;-)
