## Description:     Sharp MZ series ROM assembly tool
##                  This script takes Sharp MZ ROMS in assembler format and compiles/assembles them
##                  into a ROM file using the GLASS Z80 assembler.

##
## History:         August 2018   - Initial script written.
##                  March 2021    - Updated to compile different versions of Microsoft BASIC.
