Quite a few of us fervently wish that there were.
If Chin would release the source code, I expect that there would be a
Linux version in short order. It's a shame that all Chin's hard
work is going to be lost if he does not release the source. That seems
to be the fate of a lot of software packages. For one reason or another,
the author stops development, but never releases the source. The
package then slowly loses users as it gets more and more out of date.
It's a real waste, and I don't know why it's so common.
