aha, I see some cruft now
oops....
yes, that's not meant to be in...

that's why the patch was so huge, dammit :((((

It makes it more entertaining.  And, if we do something like 
F_SHIP_BUSTER, it will be more effective too.

I really want to stay in line with the rest of the building code as long 
as it is not critically stupid.  Then we'd have to design a good 
system for preventive building.

yes...  I'm not sure what is the best way to choose techs.

very right.  current reinforcement system is flawed but what isn't.
SAM is checked for automatically in get_defence (or vulnerability) things.

I use the standard want equation (meaning that on average we'd be better 
off after attacking)

oops this is very bad.  I really need the savegame!

not my fault I suspect

defenitely not my fault: happens all the same without the aircraft code, 
when battleships empty the cities.  it's ridculously stupid.
