+tg remote
+~~~~~~~~~
+ Register given remote as TopGit-controlled. This will create
+ the namespace for the remote branch bases and teach 'git fetch'
+ and 'git push' to operate on them.
+
+ It takes a mandatory remote name argument, and optional
+ '--populate' switch - use that for your origin-style remote,
+ it will seed the local topic branch system based on the
+ remote topic branches. '--populate' will also make 'tg remote'
+ automatically fetch the remote and 'tg update' to look at
+ branches of this remote for updates by default.
