+* [hlsimple](http://pivot.cs.unb.ca/git/?p=ikiplugins.git;a=blob_plain;f=IkiWiki/Plugin/hlsimple.pm;hb=HEAD) is a wrapper for the the perl module Syntax::Highlight::Engine::Simple.  This is pure perl, pretty simple, uses css. It ought to be pretty fast (according to the author, and just because it is not external).
+On the other hand, there are not many predefined languages yet.  Defining language syntaxes is about as much
