// Registration for kbmMemTable extended by Chris G. Royle to support
// Delphi 5 Categories.
//
// Between versions 1.37 and the current version, many new features / properties have
// been added. Categorisation helps newbies & upgraders make the transition.
//
// Note that the Advanced, and File Categories default to being non-visible after a build.
