# @BLURB: Eclass to support elisp packages distributed by XEmacs.
# @DESCRIPTION:
# This eclass supports ebuilds for packages distributed by XEmacs.
# @ECLASS-VARIABLE: XEMACS_PKG_CAT
# @REQUIRED
# @DESCRIPTION:
# The package category that the package is in. Can be either standard,
# mule, or contrib.
# @ECLASS-VARIABLE: XEMACS_EXPERIMENTAL
# @PRE_INHERIT
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set then the package is downloaded from the experimental packages
# repository, which is the staging area for packages upstream. Packages
# in the experimental repository are auto-generated from XEmacs VCS, so
# they may not be well-tested.
