Difference of Ajax Libraries / Frameworks / Toolkits

I just listed a bunch of Ajax frameworks, libraries, and toolkits ... I just realized I need to go back a step... what is the difference among them? These are the differences how I see them; it's not an official definition, but just explaining the differences in simple words.

Library: consists only of a series of functions.
example: Dojo, prototype, script.aculo.us

Framework: library plus methodology, event or process management, and other utilities that facilitates writing a program.
example: Fusebox, Model Glue, Mach II

Toolkit: framework plus an IDE. It's a complete solution for your needs.
example: Microsoft Atlas, Ticbo GI, Zimbra AT.


So anyways, Adobe is developing their version of an Ajax Library called Spry. Ray Camden seems to like it. I haven't tried it yet, but I will sometime this upcoming week. Not sure why Adobe is even interested in getting in this game, unless they have some big plans of taking this library and allowing for creating Ajax pages with server side calls through ColdFusion ... I'll post more on this soon.
