+
+  git push origin $BRANCH:users/$USERNAME/try-$BRANCH

-  git commit -a -m "Awesome hack"
-  git push origin <your-branch>:users/<your-user-name>/try-<your-branch>

-When all builders have build your patch the buildbot will sent you (or
-actually the patch author) an email telling you if any builds failed and
-references to all the logs. You can also find the logs and the builds here:
-https://builder.sourceware.org/buildbot/#/builders?tags=valgrind-try
+The buildbot will also sent the patch author multiple success/failure emails.

-    git push origin :users/username/try-<your-branch>
+    git push origin :users/$USERNAME/try-$BRANCH
