+                          them again.
+ --force                  Bootstrap even if the sources didn't come from CVS.
+ --skip-po                Do not download po files.
+ --cvs-user=USERNAME      Set the CVS username to be used when accessing
+                          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.
