+#
+# Invalid projects are removed from the returned list if and only if you

+#   ensures that 'descr_long' and 'ctags' fields are filled
+# * @project_list = fill_project_list_info(\@project_list)
+#   ensures that all fields are filled (and invalid projects removed)

 # NOTE: modifies $projlist, but does not remove entries from it
