+# This is an example wrapper script for `labwc-menu-generator` which aims to
+# demonstrate how a user can customize the menu with entries before/after the
+# directories and to ignore certain applications.
+#
+# `labwc-menu-generator` does the hard work of parsing system application
+# .desktop files and categorizing them into directories. Technically it would
+# of course be possible to add options for further customisation such as what
+# is achieved by this script, but that would mostly likely result in a couple
+# of undesireable outcomes:
+#
+# 1. Significantly extend project scope to cater for unusual and obscure
+#    requirements (including translations), thus making it harder to maintain
+#    and less likely to survive in the long-run.
+#
+# 2. Make the user-interface disproportionately more complicated compared with
+#    writing a simple wrapper script.
