UNIT TESTS FOR ZEN GRIDS
------------------------
To run the unit tests for Zen Grids:
1. Create a "tests" Compass project using the unit-tests pattern:
compass create tests -r zen-grids --using=zen-grids/unit-tests
2. From inside the "tests" project, compare the compiled stylesheets to the
previous unit test results in the test-results directory:
diff -r test-results/ stylesheets/
If the unit tests were successful, the above command should report no
differences.
