+# Workaround for the fact that cpack's filenames are not customizable.
+# Each add-on is added as a separate component to facilitate zip/tgz packaging.
+# The filenames are always of the form basename-component, which is 
+# incompatible with the addonid-version scheme we want. This hack renames
+# the files from the file names generated by the 'package' target.
+# Sadly we cannot extend the 'package' target, as it is a builtin target, see 
+# http://public.kitware.com/Bug/view.php?id=8438
+# Thus, we have to add an 'addon-package' target.
