########################################################################
# We assume the following naming convention, because that is what the
# docs currently seem to use.
#
# <filename>-<locale>.<ext> is a language-specific file, such as
# "foo-en.png".
#
# <filename>.<ext> is a language-neutral file, such as "foo.png".
#
# What makes this complicated is that some files already have embedded
# dashes that have nothing to do with locales, thus we have an ambiguous
