This is an incomplete attempt to write regression tests for ajdoc by comparison with javadoc. It aims to run both tools against the same pure-java sources and compare the output line-by-line, assuming they should be the same where non-AspectJ elements are concerned.

It relies entirely on CLASSPATH and PATH being set correctly, and it generates output directory in the current working directory.

General example of how to run:

- Compile the sources
- Setup CLASSPATH, including compiled sources and JDK tools.jar (for javadoc)
- Setup PATH, so that "java" invokes a 1.2 or later java vm
- Invoke from the directory with input/ as a subdirectory:
