# 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.

# Specify if cmake buildsystem is being used. Possible values are 'always' and 'never'.
# Please note that if it's set to 'never' you need to explicitly override following phases:
# src_configure, src_compile, src_test and src_install.
# Defaults to 'always'.
