    1.32 +/**
    1.33 + * Runs javadoc and then runs regression tests on the resulting output.
    1.34 + * This class currently contains three tests:
    1.35 + * <ul>
    1.36 + * <li> String search: Reads each file, complete with newlines,
    1.37 + *      into a string.  Lets you search for strings that contain
    1.38 + *      newlines.  String matching is case-sensitive.
    1.39 + *      You can run javadoc multiple times with different arguments,
    1.40 + *      generating output into different destination directories, and
    1.41 + *      then perform a different array of tests on each one.
    1.42 + *      To do this, the run method accepts a test array for testing
    1.43 + *      that a string is found, and a negated test array for testing
    1.44 + *      that a string is not found.
    1.45 + * <li> Run diffs: Iterate through the list of given file pairs
    1.46 + *      and diff the pairs.
    1.47 + * <li> Check exit code: Check the exit code of Javadoc and
    1.48 + *      record whether the test passed or failed.
    1.49 + * </ul>
