     RC files are PHP-GTK's method for setting the default look and feel for
     and application, class of widgets, or an individaul widget. When an
     application loads you can tell it to parse an rc file that acts similar
     to a style sheet for GTK objects. It defines how widgets should appear in
     their default state (before any user code alters their appearance). For 
     more details about rc files, including their format, see
