(keitai-l) Command line question

Hi,

I am wanting to create a jam file using Antenna because I can do
pre-processing with my code, but am not sure how to go about this to get a
jam file. I have my source code ready to go and just need to know how I can
create a jam file on the command line either with the doja emulator or with
anything else.

Is someone able to offer me some help or point me in the right direction?

Donna
