This script and build target will take the revision number from a Subversion repository (or a Git
repository using git-svn) and substitute the last dotted component of the CFBundleVersion in your
Info.plist file (you can put something like "1.0.0.xx" for your first run).

Instructions:

- Save update_build_number.rb into ${PROJECT_DIR}/Scripts (or wherever you want, but remember to
  change the paths accordigly in the build phase).
- Add a new target to your project (I named mines as "Update FooBar Build Number"). In new target
  dialog choose from "Other" category "Shell Script Target".
