I should remove layout-subsite-integration from CVS.
Richard, the history here is that after writing layout-subsite-integration, I got some funding from MGH to add the "package extension" feature to OpenACS 5.5.0.
This allows a much better integration of related packages into a holistic new package. layout-managed-subsite extends both acs-subsite and layout-manager (think of package extension as being a primitive kind of inheritance, including multiple inheritance).
This made layout-subsite-integration obsolete.
