[horde] Wicked custom macro

[Zimler Attila Tamás]

Dear List,

I would like to integrate a custom php code into the wiki application 
with the same mechanism as used for [[toc]]. I tried to search the web, 
the list archives of wiki and horde lists, and I also tried to read the 
code of wicked but I don't have any clue how to implement a new macro.

Could somebody point me in right direction?

My goal is simple, I would like to implement a custom functionality in 
wicked that would result in [[mymacro parameters]] to replaced by an 
output of a php script.

Thanks for the great piece of software,
Attila
