 *      PACKAGE:  [incr Tcl]
 *  DESCRIPTION:  Object-Oriented Extensions to Tcl
 *
 *  [incr Tcl] provides object-oriented extensions to Tcl, much as
 *  C++ provides object-oriented extensions to C.  It provides a means
 *  of encapsulating related procedures together with their shared data
 *  in a local namespace that is hidden from the outside world.  It
 *  promotes code re-use through inheritance.  More than anything else,
 *  it encourages better organization of Tcl applications through the
 *  object-oriented paradigm, leading to code that is easier to
 *  understand and maintain.
 *
 *  These procedures handle built-in class methods, including the
 *  "isa" method (to query hierarchy info) and the "info" method
 *  (to query class/object data).

 *  Handles the following syntax:
 *
 *    <objName> configure ?-<option>? ?<value> -<option> <value>...?
 *
 *  Allows access to public variables as if they were configuration
 *  options.  With no arguments, this command returns the current
 *  list of public variable options.  If -<option> is specified,
 *  this returns the information for just one option:
 *
 *    -<optionName> <initVal> <currentVal>
 *
 *  Otherwise, the list of arguments is parsed, and values are
 *  assigned to the various public variable options.  When each
 *  option changes, a big of "config" code associated with the option
 *  is executed, to bring the object up to date.
