At this point the parser is just a proof of concept. For those brave
enough, however, I've put the code on github:


The "test.mk" file provides some test cases. To get an input big
enough to measure multiple thread performances, you can concatenate
that file a few thousand times: the timings in my previous message
were obtained parsing a 3000x concatenation (final size: 1.1 MB).
