Yeah, but I think we can take care of these use cases with more modern, 
better maintained and more clearly licensed libraries than z3c.javascript.

I'm not sure what you mean here. But I'll try to answer anyway.

The way I'd do it these days is follow the pattern of hurry.yui (I 
created that, so I'm biased. Based on hurry.resource).

For instance, you want to use the YUI 'datatable' library (and all that 
it depends on) in your Grok project, you'd do the following:

* depend on hurry.zoperesource and hurry.resource

* depend on hurry.yui and hurry.zopeyui (I want the latter to go away as 
it's not pulling its weight as a package, move the configure.zcml into 
hurry.yui, even though hurry.yui is zope-independent it won't hurt)

* then in your code (say, a widget or a template) say something like:

   from hurry.yui import datatable

   ...in widget or update() method of template or whatever is a 
side-effect of rendering...

    datatable.need()

    ...

Yes, that was understood, but thanks for making sure.

Yes, agreed exactly. I think we should make it much simpler. hurry.yui 
for instance only pulls in the YUI license, which is fairly obvious 
(though hurry.yui as it is in svn.zope.org doesn't *include* YUI 
directly; it's only included upon release. so hurry.yui is actually ZPL. 
a bit confusing, but hopefully not too much).
