_D_e_s_c_r_i_p_t_i_o_n:

     Constructs an object of class 'classRepresentation' to describe a
     particular class.  Mostly a utility function, but you can call it
     to create a class definition without assigning it, as 'setClass'
     would do.

_U_s_a_g_e:

     makeClassRepresentation(name, slots=list(), superClasses=character(),
                             prototype=NULL, package, validity, access,
                             version, sealed, virtual=NA, where)

_A_r_g_u_m_e_n_t_s:

    name: character string name for the class

   slots: named list of slot classes as would be supplied to
          'setClass', but _without_ the unnamed arguments for
          superClasses if any.

superClasses: what classes does this class extend

prototype: an object providing the default data for the class, e.g, the
          result of a call to 'prototype'.

 package: The character string name for the package in which the class
          will be stored; see 'getPackageName'.

validity: Optional validity method.  See 'validObject', and the
          discussion of validity methods in the reference.

  access: Access information.  Not currently used.

 version: Optional version key for version control.  Currently
          generated, but not used.

  sealed: Is the class sealed? See 'setClass'.

 virtual: Is this known to be a virtual class?

   where: The environment from which to look for class definitions
          needed (e.g., for slots or superclasses). See the discussion
          of this argument under GenericFunctions.
