Under Release 2 (V36), the way Preferences are handled is significantly
different.  No longer is there one Preferences program with one
configuration file.  Instead there can be any number of Preferences
editors (there are currently 13), each with its own separate configuration
file covering a specific area.  All these Preferences editors have the
same look and feel.  Using separate Preferences editors and configuration
files allows for adding new Preferences items (and editors) in future
versions of the OS.
