Well, in the end, rather than fold my code into CGI::Wiki and its example scripts, Kake has persuaded me to release the thing as an actual module. So, the world now has CGI::Wiki::Formatter::Kwiki and CGI::Wiki::Kwiki. I'm not sure about the name of the latter, but given that is was mostly written as a Kwiki importer and front end, it made the most sense. I hope that people also realise that it doesn't have to have anything to do with Kwikis at all, and can be used as a stand-alone wiki front end..
They still have very small version numbers, the formatter needs code, tables and comments, and the Wiki front-end needs tests (bad me), but as far as I can tell, for the most part they both work. The code is much cleaned up from the "last release":/blog/programming/CGI-Wiki, all modular and everything, I'm much happier with it now.
You can get them both from CPAN.
