To build this program as supplied, you will need a Windows PC with Virtual T (v1.7)
and mingw installed.

To completely build this program:
1. open z100asm\z100asm.prj in the Virtual T (v1.7) IDE
2. build the z100asm project
3. in a command window, cd to the z100pkg directory and run build.bat

This produces the packaging program z100pkg.exe which can be used to package a
version 3 z-code game into blocks for use with REX.

*** NOTE ***
Depending on your version of REX, you may need to modify the value of
namdir
in z100.asm before building.  Use
namdir equ 04400h
for REX v4.8, and use
namdir equ 06400h
for REX v4.9 +.
