# @MAINTAINER:

# @BLURB: This eclass provides functions for kde 4.X ebuilds
# @DESCRIPTION:
# The kde4-base.eclass provides support for building KDE4 based ebuilds
# and KDE4 applications.
#
# NOTE: KDE 4 ebuilds currently support EAPIs 4 and 5.  This will be
# reviewed over time as new EAPI versions are approved.

# add a dependency on sec-policy/selinux-${KDE_SELINUX_MODULE} to (R)DEPEND

# For proper description see virtualx.eclass manpage.
# Here we redefine default value to be manual, if your package needs virtualx
