Here's "minrexx", a simple ARexx interface which can be easily patched into
almost any program, and an example from Fish Disk 1, where I add an ARexx
port to freedraw.

For documentation on Minrexx, refer to the .c and .h file.

For documentation on the Freedraw port, see the portions of freedraw.c
delimited by "#ifdef TALKTOREXX".

Enjoy!
