Explain this bit for me.

Code:
Constantinople_Province
	Constantinople
	byzantium
	Greek_Rebels
	118 131 33
	grain, dyes, silk, crusade
	5
	4
	religions { catholic 0 orthodox 95 islam 2 pagan 2 heretic 1 }

Explain the following to me..

What do the numbers mean

118 131 33

5

4

And am I correct in my assumption that the line

grain, dyes, silk, crusade

means that constantinopel trades grain, dyes, silk and is a potential crusade target ??

Trying to get a grip on these things as I have an idea for a mod, but first I want to do some groundwork for people.
