# @BLURB: Use this to easy install EMBOSS and EMBASSY programs (EMBOSS add-ons).
# @DESCRIPTION:
# The inheriting ebuild must set at least EAPI=5 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="5"
#
# EBO_DESCRIPTION="applications from the CBS group"
#
# inherit emboss-r1

# @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.

# @ECLASS-VARIABLE: EBO_EXTRA_ECONF
# @DEFAULT_UNSET
# @DESCRIPTION:
# Extra config options passed to econf.
