# TODO: We need a way to assign multiple extras to a arbitrarily named metapackage. But a good format for the environment variable to do this escapes me.
#	something like:
#		mymetapackage1: extra1 extra2 mymetapackage2: extra3 extra4
#		mymetapackage1 (extra1 extra2) mymetapackage2 (extra3 extra4)
# 	or using one metapackage per line:
#		mymetapackage1: extra1 extra2
#		mymetapackage2: extra3 extra4
# Not sure...

# Now for the real work
# XXX - do we really have to run this multiple times? can dependencies ever differ for different python versions?
#		Yes, they can. setup.py is a program and can generate any dependencies depending on the python used to run it.
#		We should make sure we depend on all them, if there's a case that doesn't work like that, probably best would be to manage dependencies by hand
#		rather than modify dh_pydeb
