/**
* JavadocAssertionTestSuite will dynamically create test cases from Groovy assertions placed within
* Javadoc comments. Assertions should be placed within an html tag with a class="groovyTestCase"
* attribute assignment. Example:
* <pre class="groovyTestCase"> assert "example".size() == 7 </pre>
*
* Source files will be read from the directory specified by the javadocAssertion.src.dir
* system property, including all files matching javadocAssertion.src.pattern and
* excluding files matching the javadocAssertion.src.excludesPattern.
*
* By default all .java and .groovy source files from ./src will
* be scanned for assertions.
*
* You can also run this class as an application from the command line (assumes Groovy, JUnit and Ant
* are on the classpath). As an example:
*
*
* java groovy.util.JavadocAssertionTestSuite src/main
*
*
* Note: this class requires the Ant module at runtime.
