+# @BLURB: An eclass that helps automating the creation of ebuilds for software only distributed through rpm
+# @DESCRIPTION:
+# This extends the rpm eclass to also installs *all* files in the rpm,
+# and extracts post/pre(un)install scripts and runs them.
+#
+# This is mostly useful when creating ebuilds for rpm files in bulk.
+# In cases when it is not doable to write a Gentoo specific src_install
+# and pkg_post/pre/install/rm functions for each ebuild.
+
+# The rpm eclass provides the pkg_unpack function we need
+inherit rpm
