+# 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+"
+#
