# @BLURB: Support eclass for packages that follow KDE packaging conventions.
# @DESCRIPTION:
# This eclass is intended to streamline the creation of ebuilds for packages
# that follow KDE upstream packaging conventions. It's primarily intended for
# the three upstream release groups (Frameworks, Plasma, Applications) but
# is also for any package that follows similar conventions.
#
# This eclass unconditionally inherits kde5-functions.eclass and all its public
# functions and variables may be considered as part of this eclass's API.
#
# This eclass unconditionally inherits cmake-utils.eclass and all its public
# variables and helper functions (not phase functions) may be considered as part
# of this eclass's API.
#
# This eclass's phase functions are not intended to be mixed and matched, so if
# any phase functions are overriden the version here should also be called.
