rockbox/utils/parse_testcodec.rb
Thomas Martitz dc521b5d48 Replace parse_testcodec.pl with a bit more powerful script.
It can compare more than one result file at a time giving additional speedup colums, is more robust
(RaaA results don't have the "MHz needed for realtime" line which is handled with this one) and
has a mode to output the results in a form readable by spreadsheet software for nice graphs.
Needs Ruby 1.9.x
