Migrated over changes to move some GIF resources into a common subdirectory in the subsite package, so anyone who can read the main site can read the images (previously you had to grant read privs to "/doc" explicitly to get the graphics stored by acs-datetime to show up.
changing to no longer read/write file listings and database support from/to info files. This info is now determined directly from the paths in the file system (see procs apm_get_package_files and apm_package_supports_rdbms_p)
