# KNOWN ISSUES:
# - Translations may not work.  I've been unsuccessful in forcing
#   localized output.  Anyway, upstream (Canonical) doesn't install the
#   message files.

# TODO:
# - since 0.15 gccgo is a supported compiler ('make gccgo').  It would
#   be preferable for that support to go into the golang-build eclass not
#   this package directly.
