This port of frotz to the BeOS was performed by Stephen van Egmond.

Both were built with beta versions of Release 4 for the PowerPC and
Intel processors.  They should work with the shipping version of R4
as well.

The PowerPC version should be binary compatible as far back as Preview
Release 2.  If this turns out to not be the case, please let me know.

The x86 vesion will only work with R4 or better.  Be has broken binary 
compatibility between R3 and R4.

Information on how this port was built can be obtained by mailing
