+tg base
+~~~~~~~
+       Prints the base commit of the current topic branch.  Silently
+       exits with exit code 1 if you are not working on a TopGit
+       branch.  The following command can be useful to get a summary
+       of the work you have made on a topic branch:
+
+               git log --first-parent --no-merges `tg base`..
+
+       (Note: if you have shared the TopGit branch, the above command
+       only lists the commits that were made in the current
+       repository, so you will not see work done by your
+       collaborators.)
