+# @BLURB: Support eclass for packages that use KDE Frameworks with ECM.
+# @DESCRIPTION:
+# This eclass is intended to streamline the creation of ebuilds for packages
+# that use cmake and KDE Frameworks' extra-cmake-modules, thereby following
+# some of their packaging conventions. It is primarily intended for the tree
+# upstream release groups (Frameworks, Plasma, Applications) but also for any
+# other package that follows similar conventions.
+#
+# 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 overridden the version here should also be called.
+#
+# Porting from kde5.class
+# - Convert all add_*_dep dependency functions to regular dependencies
+# - Manually set LICENSE
+# - Manually set SLOT
+# - Rename vars and function names as needed, see kde5.eclass PORTING comments
+# - Instead of FRAMEWORKS_MINIMAL, define KFMIN in ebuilds and use it for deps
