Reading scripts in monochrome was displeasing me, so I have begun to adapt the CRPL syntax highlighter file. So far, I have deleted the CONST_ and recognised "*", "[", "." and "]". I have also set it up to allow folding of multiline comments.
File attached, usage instructions exactly as for the CRPL syntax highlighter.
When the wiki PRPL section is nigh-finished well-started, this can go there.
