The scripter project can enter a new phase now.
I've just completed building the setup (2.38 MB only) of a complete script compiler, that will create playable missions.
The only thing NOT included yet is tube placement (not entirely true - you can place them 1 at a time using the UNIT TUBE command). This means that all buildings must be adjacent for this to work at the moment.
For now, i stuck to AIS for extention, but as i promised: you guys can vote!
