Updated for iLib, and added many new rows for various i18n features. Other libraries slots need to be updated to put the check marks for all these new features.
Perhaps "slavic plurals" is not the best name for it. Slavic languages make the most use out of this feature, though. The idea is that there are more classes of plurals than the basic "singular" and "plural" in English.

In English: 

When there are no objects, you write "0 objects". Note that "objects" is plural for some crazy reason.
When there is one object, you write "1 object". Singular.
Everything else is the plural case. "There are 434,345 objects."

In French:

Zero objects is singular. 
One object is singular.
Everything else is plural.

In Russian:

One object is singular in the "one" class. eg. "1 объект"
Two to four objects is in the class "few", which gives a particular ending to the noun. eg. "2 объекта"
Five to nine objects is in the class "many", which gives a different ending to the noun. eg. "5 объектов"
Zero objects is in the many class. "0 объектов"
Any number where that number mod 10 == 1 is in the "one" class, EXCEPT numbers where the number mod 100 == 11.  eg. 41 is "41 объект", but 111 is "111 объектов"
Any number where that number mod 10 == 2 to 4 is in the "few" class EXCEPT numbers mod 100 == 12, 13, or 14 which are in the "many" class instead. eg. 52 is "52 объекта" but 112 is "112 объектов"

Other slavic languages are similarly complicated, but with different rules governing which numbers are in which class.
