# ----- metaprogramming (translators, pleaee ignore all this) -----
#
# We present translators with a single file po/messages.pot containing
# all the messages for the translated programs in dgit.deb and
# git-debrebase.deb. This also includes the messages from the shared
# perl modules.
#
# But when we make the .debs, we want to ship in each .deb the
# messages for that .deb, only (but including the common parts).
#
# So we generate three intermediate .pots,
# .{dgit,git-debrebase,common}.pot
# and merge them to make messages.pot.
#
# From the translations we generate two .mo files for each output
# language: {dgit,git-debrebase}.mo -- including the common messages.
#
# To avoid dirtying the tree whenever we do `make install',
# we honour SUPPRESS_PO_UPDATE, to be used like this
# make install prefix=$(prefix) SUPPRESS_PO_UPDATE=1
