- This plugin makes PhpWiki v1.3.x database tables accessible for ewiki.
- It is mainly used for conversion from PhpWiki to ErfurtWiki - and you
- should not rely on it for daily work, as the PhpWiki tables will
- probably always become inconsistent due to the rather simple access
- approach used herein.
-
- The code is mainly based upon the PhpWiki database scheme and some
- experiments with an existing setup (after five hours of PhpWikiSetup).
- You must first enable write access - working, but not well tested.
