is to use shell scripts to generate everything. * Each emulation is defined by a short shell script with extension *.sh that specifies the emulation-specific parameters (such as the name of the *.sh-sc and *.em files to use). * genscript.sh is the master shell script used to generate an emulation. It is passed various argument, including the name a the emulation-speciic *.sh file that it "sources" to set variables to emulation-specifc parameters.
