+
+switch_maint_mode reverses the status of AM_MAINTAINER_MODE in
+configure.ac from enable to disable or vice-versa. When enabled,
+this feature forces the autotools to run when the input files are
+older than the output files. This is the default for development
+branches. When disabled, the autotools will NOT be re-run regardless
+of their timestamps or any modifications. This is the default for
+tarballs and release branches since it avoids having end-users
+requiring the autotools.
