+The ultimate goal of Parrot is portability to more-or-less the same +platforms as Perl 5, including AIX, BeOS, BSD/OS, Cygwin, Darwin, +Debian, DG/UX, Domain/OS, DragonFlyBSD, DYNIX/ptx, Embedix, EPOC, +FreeBSD, Gentoo, HP-UX, IRIX, Linux, Mac OS (Classic), Mac OS X, +Mandriva, Minix, MS-DOS, NetBSD, NetWare, NonStop-UX, OpenBSD, OS/2, +Plan 9, Red Hat, RISC OS, Slackware, Solaris, SuSE, Syllable, Symbian, +Tivo (Linux), Ubuntu, VMS, VOS, WinCE, Windows +95/98/Me/NT/2000/XP/Vista, and z/OS.
As far as I known, Debian, Red Hat etc. all are Linux distributions, so what's the exactly mean of Linux as a different platform?
