+# - Find tools needed for building RPM Packages
+# on Linux systems and defines macro that helps to
+# build source or binary RPM, the MACRO assumes
+# CMake 2.4.x which includes CPack support.
+# CPack is used to build tar.gz source tarball
+# which may be used by a custom user-made spec file.
+#
+# - Define RPMTools_ADD_RPM_TARGETS which defines
+# two (top-level) CUSTOM targets for building
+# source and binary RPMs
+#
+# Those CMake macros are provided by the TSP Developer Team
+# https://savannah.nongnu.org/projects/tsp
+#
+# Modified by Werner to use the SoureDistribution variables and
+# files instead of CPack stuff. Only minor changes.
