   2 # This script can be used to implement syntax highlighting in the cgit
   3 # tree-view by refering to this file with the source-filter or repo.source-
   4 # filter options in cgitrc.
   5 #
   6 # This script requires a shell supporting the ${var##pattern} syntax.
   7 # It is supported by at least dash and bash, however busybox environments
   8 # might have to use an external call to sed instead.
   9 #
  10 # Note: the highlight command (http://www.andre-simon.de/) uses css for syntax
  11 # highlighting, so you'll probably want something like the following included
  12 # in your css file:
