Cool, thanks! I've applied grml-policy-backticks-block.txt and it's available 
online at http://grml.org/policy/ already.

Regarding grml-policy-backticks-source.txt: hm, does not look like the "source-
highlight for colored source snippets" works here. Do I need any special 
asciidoc version/option to use that feature? Or did I just miss anything? :)

thx && regards,
