	Some things that I learned from the manual that are not
easily deduced:
	
	LOVE THE PRESIDENT DAY occurs when as many or more people
are happy as content, no unhappies, and city size > 3
	LOVE THE PRESIDENT DAY in despotism makes the city funciton
as monarchy, in monarchy or communism makes perform as republic, 
in republic or democracy makes citie go up one pop level each turn.
	Communism makes corruption equal for all cities.
	Republic makes +1 trade where 1 exists but martial law
is no longer possible and unit out of home citie makes 1 unhappy.
	Democracy eliminates corruption but makes 2 unhappies for
units out of home citie.
	Barracks cost 0,1,2 after gunpowder and combustion.
	You can eliminate enemies spaceship by taking their capital.
	Factories stop working after manufacturing plant is built.
	Diplomats & caravans cost no maintainence or unhappies in re/de
	Diplomats can subvert (buy) cities.
	Excess pollution causes global warming which results in swamps.
	In democracy, a citie in revolt may cause the entire civilization
to revolt. Also, revolting citie has chance of nuclear meltdown.
	Artillery and bombers are not attenuated by citywalls.
	The advisors of enemies stand behind them. From their advisors
you can tell their government and size relative to all players.
	50% chance of production unit being on river. No way to tell until
you build near there.
	Railroad increases land production by 50% rounded down.
	You cannot sell wonders. Wonders are not destroyed by attacks
unless the entire citie is destroyed. Other citie improvements can be
sold by clicking on red dot to their right. Only one improvement per citie
per turn.
	Repub/demo will always accept enemies treaties, and never allow you
to break them.
