Gitweb: add support for Alex Gorbatchev's SyntaxHighlighter in Javascript
Gitweb is not exactly what you would call server-friendly, so let's offload one more task onto the client. To enable this, put something like this into your gitweb_config.perl: $feature{'syntaxhighlighter_js'}{'default'} = [{ url => '/SyntaxHighlighter/', style => 'Django', theme => 'FadeToGrey' }]; and clone git://github.com/alexgorbatchev/SyntaxHighlighter into the directory you specified via the 'url' parameter.
