Hi Phil. No problem, pull request to merge with v0.4devel this time.
Cheers
They are in the order expected by CF::Helpers::load_runfile_params so that I can lazily use that to parse @ARGV in my .cfmod wrappers. In the end I guess I am mainly interested in extracting $files and $@parameters to estimate memory needs, but didn't want to leave out anything that someone else might find useful.
