The project true to its name runs on a variety of platform including Linux,Hurd and Cygwin GNU systems. To avoid any legal problems Pnet has decided to go the hard way and bootstrap our compiler off gcc. Unlike Mono which uses microsoft's runtime to run their compiler. Our premier developer Rhys Weatherly has contributed 254,423 lines written since Jan 1, 2001. Which amounts to about 5000 lines per week which is phenomenal for any programmer. He is dotGNU's one-man army. So join him in celebrating his quarter billion lines of his code." Update: 12/27 02:41 GMT by T : Note that as many readers have pointed out, that's just like the headline says -- a quarter million lines, rather than billion. Some related links to check out include the dotGNU home page, the Southern Storm Software (Rhys Weatherley's shop, with Portable .NET information), Mono's page and Pnet's CVS repository.
