Finally! Our next, and last, UCC release! We have decided to focus on UCC-Java, so that it has all the features UCC currently does. Hence, I have decided to make this release available to everyone.
Release notes, user manual are available as PDFs. Also you can find line count and cyclomatic complexity metric calculation rules in Counting Rules subdirectory.
The tool successfully compiles under Linux, yet it's somewhat buggy and doesn't provide complete support for modern languages' standards.
