// Description : This is an abstract base class that defines how to

// generate code that can be called from an external
|
|
// language (like Python or Squeak) and that can call
|
|
// into Panda.
|
|
//
|
|
// The specializations of this class like
|
|
// InterfaceMakerPython and InterfaceMakerC will
|
|
// generate the actual wrappers for the various language
|
|
// calling conventions.
