+ --force                  Attempt to bootstrap even if the sources seem

+ --skip-po                Do not download po files.
+ --cvs-user=USERNAME      Set the username to use when checking out
+			  sources from the gnulib repository.
+
+If the file bootstrap.conf exists in the current working directory, its
+contents are read as shell variables to configure the bootstrap.

+Running without arguments will suffice in most cases.
