First of all I'd like to apologize for posting this question in main hall, but nobody seems to care about modification forum anyway, so I'll leave it for the moderators...

Does anyone know what are the differences in faction behaviours stated
in a startpos file? There is some quite confusing stuff there... For instance, the ultra agressive Almohads have been stated as muslim_peaceful. There are also behaviours that are not used at all such as poverty_stricken or desperate_defence.
Also can one give the Poles the crusading ability by stating them as catholic_defensive_crusader or similar?

thnx!
