# @BLURB: Common ebuild functions for monolithic and split KDE 4 packages
# @DESCRIPTION:
# This eclass contains all functions shared by the different eclasses,
# for KDE 4 monolithic and split ebuilds.
#
# NOTE: This eclass uses the SLOT dependencies from EAPI="1" or compatible,
# hence you must define EAPI="1" in the ebuild, before inheriting any eclasses.

# @ECLASS-VARIABLE: KDEBASE
# @DESCRIPTION:
# This gets set to a non-zero value when a package is considered a kde or
# koffice ebuild.

if [[ "${CATEGORY}" == "kde-base" ]]; then
	debug-print "${ECLASS}: KDEBASE ebuild recognized"
	KDEBASE="kde-base"

# is this a koffice ebuild?
if [[ "${KMNAME}" == "koffice" || "${PN}" == "koffice" ]]; then

# @ECLASS-VARIABLE: KDE_DERIVATION_MAP
# @DESCRIPTION:
# Map of the monolithic->split ebuild derivation.
# Used to build dependencies describing the relationships between them:
# Monolithic ebuilds block their split counterparts in the same slot, and vice versa.
#
# Also see get-parent-package(), get-child-packages(), is-parent-package()
