the apt format is VERY simular to the wiki formats (see http://maven.apache.org/guides/mini/guide-apt-format.html )
The APT format is used in maven-2 to write project sites and descriptions. With very little adaptation this format could be supported and the use for this plugin would spread suddenly to all maven projects!
There is also a tool named aptconvert that can be used to generate pdf,rtf....,html from apt. http://www.xmlmind.com/aptconvert.html
