This sample recipe builds using a monotone repository.

Comments:

• Note that the above recipe uses the ${repository.branch} variable to specify the monotone branch. Either specify in the slave configuration (see example at Slave Configuration), or replace the variable name with a literal branch name in the recipe.
• Checkout: This creates a temporary directory, deleting it first to guarantee it's empty. Then, creates a local monotone repository database if it doesn't already exist. Then, synchronises with the remote repository, and finally checks out the appropriate revision.
• Compile: Just calls make.
• Test: Just calls make test.
• Cleanup: Trashes the temporary directory.
• Note that the local copy of the monotone repository is left lying around in /tmp/db.mtn. It obviously saves some network bandwidth if the repository isn't re-copied to the slave for each build, so this is worth doing. You might want to put it somewhere else other than /tmp.
