-# @BLURB: Support eclass for KDE 5-related packages.
+# @BLURB: Support eclass for packages that follow KDE packaging conventions.
 # @DESCRIPTION:
-# The kde5.eclass provides support for building KDE 5-related packages.
+# 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.
