Cleaned old stuff coming from the master charm.

9. By Francesco Banconi on 2012-01-30

Cleaned config-changed file.

10. By Francesco Banconi on 2012-01-30

Cleaned install hook.

[Gary Poster (gary)]

Thank you for cleaning out the unnecessary master changes as we discussed on a hangout.

hooks/buildbot-relation-changed will be idempotent after we move the installation to the install step, so I won't worry about that.

+summary: system to automate the compile/test cycle
+description: |
+  The BuildBot is a system to automate the compile/test cycle required by
+  most software projects to validate code changes. By automatically
+  rebuilding and testing the tree each time something has changed, build
+  problems are pinpointed quickly, before other developers are
+  inconvenienced by the failure. The guilty developer can be identified
+  and harassed without human intervention.  By running the builds on a
+  variety of platforms, developers who do not have the facilities to
+  test their changes everywhere before checkin will at least know
+  shortly afterwards whether they have broken the build or not. Warning
+  counts, lint checks, image size, compile time, and other build
+  parameters can be tracked over time, are more visible, and are
+  therefore easier to improve.

+  buildbot:
+    interface: master
