Looking for definition files (md.highlight and md.theme)

[Hans Lehmann <hans@xxxxxxxxxxxxxx>]

Hi

I am looking for definition files (md.highlight and md.theme) for the 
syntax highlighting of markdown source code in the TextEditor.
Its supposed to be used in a syntax highlighting demo app in the 
Gambas-Buch.

Can someone help or has something off the shelf?

Best regards

Hans
