# @DESCRIPTION:
# An eclass streamlining the construction of ebuilds for the officially
# supported RHVoice languages.
#
# Look at "src/scripts" files to identify language's license.
# @EXAMPLE:
#
# Most ebuilds will look like this:
#
# @CODE
#
# EAPI=8
#
# RHVOICE_LANG="Russian"
# inherit rhvoice-lang
#
# LICENSE="LGPL-2.1+"
#
# @CODE
