The environment runs under Linux on the i386 architecture. We currently use
-a slightly modified installation of Debian
-GNU/Linux, but it will happily work with any other Linux distribution with
-a 2.6 or newer kernel. The only dependecies on Linux and on i386 are in the
-sandbox module; porting to other architectures requires just minor changes,
-porting to other UNIX systems is probably hard. Outside of that, everything
-should run happily on almost any system providing a reasonable set of GNU
-utilities (especially bash) and Perl, possibly including MinGW or Cygwin on
-Windows.
