24 * The SyntaxHighlighter plugin passes all its arguments through a C++
25 * highlighter called "highlight" (available at http://www.andre-simon.de/).
29 * syntax: See http://www.andre-simon.de/doku/highlight/highlight.html
30 * style = ["ansi", "gnu", "kr", "java", "linux"]

40 I did not use beautifier, because it used up more than 8M of memory on
41 my system and PHP killed it. I'm not sure whether this is a problem
42 with my integration, or with beautifier itself.
45 support options: syntax, style, color.
