A moddable step-by-step strategy written on the shell scripts.
Besides using Unix mandatory commands it uses Bash internal functions (relatively they're extremely fast).
Right now it exactly works under xterm-based terminal emulators and tty-console. Other cases not tested yet.
I invented it with friend some years ago when we only has a pen, a pencil, an eraser, a notebook sheet and about two hours of boring free time :) .
All default files has its own remarks about modding. In future I'll standardize their structure and add normal API information file.
"*.map" is a map file. Has link to the tiles and objects to use.
"*.tls" is a file with tiles definition and handling parameters.
"*.obj" is a file containing information about units.
