To compile, use gnatmake rapid with the appropriate -I flags.  Pick only
one peer folder (e.g. -I..\tcl_peer).  Do not select the stub_peer folder.
The JVM implementation must be built from the jrapid folder.

If you don't have 3.12, then you won't be able to use
mcc.directory_operations.  Comment out the if block in rapid.adb and the
with of mcc.directory_operations.  You will not be able to specify a
filename on the command line.
