+/**
+ * A PHPUnit test case for Mustache.php.
+ *
+ * This is a very basic, very rudimentary unit test case. It's probably more important to have tests
+ * than to have elegant tests, so let's bear with it for a bit.
+ *
+ * This class assumes an example directory exists at `../examples` with the following structure:
+ *
+ * @code
+ *    examples
+ *        foo
+ *            Foo.php
+ *            foo.mustache
+ *            foo.txt
+ *        bar
+ *            Bar.php
+ *            bar.mustache
+ *            bar.txt
+ * @endcode
+ *
+ * To use this test:
+ *
+ *  1. {@link http://www.phpunit.de/manual/current/en/installation.html Install PHPUnit}
+ *  2. run phpunit from the `test` directory:
+ *        `phpunit MustacheTest` or just `phpunit`
+ *  3. Fix bugs. Lather, rinse, repeat.
+ *
+ * @extends PHPUnit_Framework_TestCase
