# @BLURB: Support eclass for packages that are hosted on kde.org infrastructure.
# @DESCRIPTION:
# This eclass is mainly providing facilities for the three upstream release
# groups (Frameworks, Plasma, Gear) to assemble default SRC_URI for tarballs,
# set up git-r3.eclass for stable/master branch versions or restrict access to
# unreleased (packager access only) tarballs in Gentoo KDE overlay, but it may
# be also used by any other package hosted on kde.org.
# It also contains default meta variables for settings not specific to any
# particular build system.
