+%prog <newbranchname> [<project>...]
+
+This subcommand starts a new branch of development that is automatically
+pulled from a remote branch.
+
+It is equivalent to the following git commands:
+
+"git branch --track <newbranchname> m/<codeline>",
+or 
+"git checkout --track -b <newbranchname> m/<codeline>".
+
+All three forms set up the config entries that repo bases some of its
+processing on.  Use %prog or git branch or checkout with --track to ensure
+the configuration data is set up properly.
