Is there a good string pluralization library for actionscript?

Question

I haven't found a good library actionscript library for this yet.

I want to do things like:

Inflection.pluralize( "cat" ) == "cats"
Inflection.pluralize( "fish" ) == "fish"

I know ruby on rails has a library like this build in; and javascript has a really nice one as well: http://code.google.com/p/inflection-js/.

Any one know of a similar thing for actionscript?
