# @BLURB: Support eclass for packages that follow KDE packaging conventions.
# @DESCRIPTION:
# This eclass is *deprecated*. Please read the PORTING notes for switching to
# ecm.eclass in case the package is using extra-cmake-modules, otherwise just
# use cmake.eclass instead. For projects hosted on kde.org infrastructure,
# inherit kde.org.eclass to fetch and unpack sources independent of the build
# system being used.
#
# 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 kde.org.eclass and either ecm.eclass if
# KDE_AUTODEPS=true (default) or cmake.eclass if KDE_AUTODEPS=false.
# All their 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 overridden the version here should also be called.
