+#!/bin/bash
+#
+# This script called in a CVS directory generates an archive in that
+# same directory, which contains all locally added new files (except
+# those rejected by the script) and a diff with all local changes.
+# This archive can then be offered to one of the CVS maintainers for
+# committing.
+#
+# Usage:
+#         $ cd $FG_ROOT/Aircraft/foo
+#         $ fg-submit      # generates foo.tar.bz2 and foo.diff
+#
+# The archive contains a copy of the diff, which is only left for
+# convenience and doesn't have to be submitted.
