32# Usage:
33# name should be of the form py-foo for modules
34# subports pyXY-foo are declared for each XY in python.versions
35
36# for apps (i.e. not named py-foo), no subports will be defined
37# only the python.default_version will be used
38# you can change that in variants if you want
39
40# options:
41# python.versions: which versions this module supports, e.g. "26 27 31"
42#   always set this (even if you have your own subport blocks)
43# python.default_version: which version will be installed if the user asks
44#   for py-foo rather than pyXY-foo
45#
46# Note: setting these options requires name to be set beforehand
