+# Either use autoconf and autoheader to create configure.sh and config.h.in
+# or (optionally) fetch the latest development versions of generated files.

+# Specify one action or more than one to provide a fall-back:
+#
+#   build     build the config files [the default w/no arg]
+#   fetch     fetch the latest dev autoconfig files
+#   fetchgen  fetch all the latest dev generated files (including manpages)
+#   fetchSRC  fetch the latest dev source files [NON-GENERATED FILES]
+#
+# The script stops after the first successful action.
