# @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 EAPI "3".  This will be reviewed
# over time as new EAPI versions are approved.

# @ECLASS-VARIABLE: KDE_SELINUX_MODULE
# @DESCRIPTION:
# If set to "none", do nothing.
# For any other value, add selinux to IUSE, and depending on that useflag
# add a dependency on sec-policy/selinux-${KDE_SELINUX_MODULE} to (R)DEPEND

# @ECLASS-VARIABLE: VIRTUALX_REQUIRED
# @DESCRIPTION:
# For proper description see virtualx.eclass manpage.
# Here we redefine default value to be manual, if your package needs virtualx
# for tests you should proceed with setting VIRTUALX_REQUIRED=test.
