Please see:
http://dev.openlayers.org/docs/files/OpenLayers/Layer/TileCache-js.html

The old docs read "A read only TileCache layer.  Used to requests tiles 
cached by TileCache in a web accessible cache."

I've just added a bit more detail - so in an hour or so, they will read 
"Used to requests tiles cached by TileCache in a web accessible cache. 
This means that you have to pre-populate your cache before this layer 
can be used.  It is meant only to read tiles created by TileCache, and 
not to make calls to TileCache for layer creation."

Maybe still a bit too subtle, but that's my specialty :)
