Plan B is written in Perl 5 using the Tk toolkit. I develop and test it under Red Hat Linux, though it should run under any version of Unix (and possibly under other platforms supporting Perl/Tk, such as the Macintosh). I'm providing the Plan B source code and a demo configuration file.
The code is truly primitive now -- not buggy, but lacking a lot of features the final product will have. When complete, it will be released under the GPL.
I expect the application to be largely self-explanatory, though
full documentation will naturally be part of the eventual release.
Meanwhile, here's the obligatory screen shot:
