+# @BLURB: Use this to easy install EMBOSS and EMBASSY programs (EMBOSS add-ons).
+# @DESCRIPTION:
+# The inheriting ebuild must set at least EAPI=6 and provide EBO_DESCRIPTION before the inherit line.
+# KEYWORDS should be set. Additionally "(R|P)DEPEND"encies and other standard
+# ebuild variables can be extended (FOO+=" bar").
+#
+# Example:
+#
+# EAPI=6
+#
+# EBO_DESCRIPTION="applications from the CBS group"
+#
+# inherit emboss-r2
+
+# @ECLASS-VARIABLE: EBO_DESCRIPTION
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Should be set. Completes the generic description of the embassy module as follows:
+#
+# EMBOSS integrated version of ${EBO_DESCRIPTION}, e.g.
+#
+# "EMBOSS integrated version of applications from the CBS group"
+#
+# Defaults to the upstream name of the module.
