# @BLURB: Use this to easy install EMBOSS and EMBASSY programs (EMBOSS add-ons).
# @DESCRIPTION:
# The inheriting ebuild must provide EBO_DESCRIPTION before the inherit line.
#
# Example:
#
# EAPI=8
#
# EBO_DESCRIPTION="applications from the CBS group"
#
# inherit emboss-r3

# @ECLASS_VARIABLE: EBO_DESCRIPTION
# @PRE_INHERIT
# @DEFAULT_UNSET
# @DESCRIPTION:
# 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.
