Wikka as a chm source generator

[DotMG]

IMHO, chm is one of the best thing Microsoft has created. Because it uses HTML format, it has good search functionnality incorporated, it has table of content and index: it is for me the best format for documentation. For writing content of documentation, wiki is the best choice as many users can modify the content at the same time: one may write the article, another checks spelling, ... To make WikkaWiki the best choice for generating a chm doc, I would implement these functionnalities, maybe some of them as a plugin :

• generating <link> headers for rel="home", rel="up", rel="previous" and rel="next". (feasible with just one action)
• using relative URL in href (suppressing the  http://site.com/ part) (demanded elsewhere also, like making the same Wikka install accessible for both intranet and internet, with 2 different URLs)
• exporting all pages in HTML format (feasible with just one handler)
• generating .hhk, .hhp and .idx files. These are used for the index

and table of contents. (yes another handler)
