It sounds like you may just want the standard Zope 3  
resourcedirectory: just makes JS, CSS, images, et al available.

z3c.zrtresource: a way to write dynamic css and js files. For  
instance, you have a css file that wants to refer to an image served  
by Zope, taking virtual hosting into account.  Particularly suitable  
for situations when you are working with a shop that has a separate  
design team.  Of course, can be effectively used in other  
environments as well.

zc.resourcelibrary: a resourcedirectory-based tool to define and use  
resources with dependencies.  For instance, one part of your  
assembled page, like a widget, needs MochiKit; another part, maybe a  
widget, needs a custom library that uses MochiKit; and another part  
needs a second custom library that depends on MochiKit.New, that  
itself depends on MochiKit; all three are assembled dynamically, and  
need to put JS/CSS code in the head, preferably without duplication,  
and in the right order.

It might be nice to have zc.resourcelibrary be able to somehow serve  
z3c.zrtresource files too...it doesn't right now.  FWIW, right now in  
lieu of zrtresource I just use <script ... tal:content="string:
/* ... JS that specifies dynamic variables and calls ... */
"></script>.  Simple, and encourages delineation between library and  
usage; but a bit hacky, and unfriendly to designers.

Other JS-related bits to know about (you'll have to do your own  
reading sometime :-): http://zif.hill-street.net/headincludes (WSGI  
variation on resourcelibrary), http://zif.hill-street.net/gzipper/  
(WSGI, gzips all output for smaller browser page sizes), http:// 
zif.hill-street.net/jsmin/ (WSGI, compresses JS for smaller browser  
page sizes), and http://svn.zope.org/z3c.javascript/ (resourcelibrary- 
aware collection of mochikit, dojo, et al).
