# @ECLASS: kde4-base.eclass
# @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 by default define EAPI="2", this can be redefined but
# eclass will fail with version older than 2.
