-# this is a direct port of exo-compos-mail-1 from xfce
-# from perl to python
-# the idea is to dump the 2000000000 perl pkgs pulled in
-# by this for a single item :(
-# it should handle all the behaviour the same
-# it probably has bugs
-
-# TODO:
-# - figure out what the attachment parsing is trying to do
-# - figure out if rebuilding the mailto for evo, sylpheed and balsa
-#    is actually necessary or not - feels silly but I'm not shocked by silly
-# - would be nice to have an actual set of tests :)
