I was discussing this with Steve on IRC.
This is another example of the small problem of cusomizing package level code. The toolkit is not designed for non-destructive cusomization.
This is an interesting case, where the main template is fine, but the include needs to be customized. For once, the behavior is well documented. in general I guess we need to be able to access tcl datasource files int he package directory and have them automatically return a customized adp from a package instance specific location.
This might require a change to the request processor to optionally skip standalone ADP files in the overriding directory, grab the package tcl file then ad_return_template would handle the custom adp page.
This would require much less copying where only formatting is changing.
