We actually had that in preliminary versions, but took it out because
it became incredibly difficult to verify. There are the Unix flavors,
Windows native, cygwin, mingw, and then potentially OS/2 and OS/X.

The support is there in the document format (it's the 4th parameter to
\begin{method} for those who're looking at the LaTeX), so if anyone
can come up with a way to work it out, we could add the information to
the printed/online book.

FWIW, I know curses runs under the cygwin version of Ruby on Windows
(such as the InstallShield one). Not sure about the others.
