 adjust these numericals value trought a black box (the generator) is a
crazzy work. no body can do something like this right. evidenttly we can
do something working but we can do it with less thant that. this is not
real freedom but a pseudo-freedom.

maybe 3 baease values to select can be apear too little but i think the
best is begin with some value 3-5 and (IF REALLY NEEDED) chngee it

(this is a bese postulat of physicist, do simple first, if this fail do
more complex) ok, ok, you known a little of physics, some one simple is
not so simple :-) 

after my work i think 5 values are ok
wetness = (oceanic, wet, medium, dray)
steepmess = (flat, hilly, abrupt)
temperature = (frizzed, cold, temperate, topical)
miselaneous = ( NeverNearCold, Low ) 
likelihood = 0-100 

likelihood is the only numerical value.
* NeverNearCold, can be used to place a dessert near tundra civ3 tileset
and is not very specific, low to place swamp (if wanted), or to best
start rivers)

we has time to compare views, i am not at this step of work, i am just
put a workable tmap, i go work in wetnes/mmap in next day. 

but think, is really so much numbers a good thing? some one exept us can
understand it? some one (us too) is really able to has real control of
this today and tomorrow(when some peuple change gen code)?

this is done in one of my patch

i need kown all restrictions plz do a list

are these restrictions needed? we can't complete the tileset to avoid
some of them?

any way , your generator is funy
