I got a little help yesterday from Dav Glass and Eric Miraglia for my issue on selection of YUI javascript files. What I'd had distributed over a bunch of files is now:

<script type="text/javascript" src="http://yui.yahooapis.com/combo?2.5.2/build/yahoo-dom-event/yahoo-dom-event.js&2.5.2/build/animation/animation-min.js&2.5.2/build/element/element-beta-min.js&2.5.2/build/container/container_core-min.js&2.5.2/build/menu/menu-min.js&2.5.2/build/button/button-min.js&2.5.2/build/connection/connection-min.js&2.5.2/build/datasource/datasource-beta-min.js&2.5.2/build/datatable/datatable-beta-min.js&2.5.2/build/tabview/tabview-min.js"></script> 

Hm... a bit better. Both Dav and Eric confirm that the canonical solution to this problem is to spend some quality time at the YUI Configuration Site which will allow you to pick the widgets and utilities you've leveraged in order to combine it into a more simplified call.

A someday project: the following style of implementation to make the reference a bit more crisp (I didn't add everything from above, but the pattern should be easy to observe):

<script type="text/javascript" src="http://yui.yahooapis.com/combo/2.5.2/dom-event&animation-min&element-beta-min&container_core-min"></script> 


Anyhow, thanks for the help.
