This program speaks to the serialdisk MacOS driver to present a disk image over the serial port.
The program expects the disk image to be in the current working directory, and named "serialfile".
This will also operate at 57600 baud, which corresponds to what the serialdisk driver version 0.2 is using.

To compile, just type "make".
This has been tested on a mac mini running SnowLeopard.

The program now has a usage statement, so that'll be the authoritative way to view how to run the program from now on.  The readme's usage was getting stale.
