DidiWiki

I modified DidiWiki vers. 0.8, it is possible to choose the color, the background color of a text or to highlight it. 

The tags are:

text color: {B}text{B}
background color: (B)text(B)
Colors available: B blue, R red, G green, C cyan, P pink, Y yellow, D black

highlight: +text+

The program (source c to compile) is here: didiwiki-0.8b
