/* */
/* Principal Programmer(s): */
/* Gary D. Riley */
/* */
/* Contributing Programmer(s): */
/* */
/* Revision History: */
/* */
/* 6.24: Renamed BOOLEAN macro type to intBool. */
/* */
/* Refactored several functions and added */
/* additional functions for use by an interface */
/* layered on top of CLIPS. */
/* */
/* 6.30: Local variables set with the bind function */
/* persist until a reset/clear command is issued. */
/* */
/* Changed garbage collection algorithm. */
/* */
/* Changed integer type/precision. */
/* */
/* Metrowerks CodeWarrior (MAC_MCW, IBM_MCW) is */
/* no longer supported. */
/* */
/* UTF-8 support. */
/* */
/* Command history and editing support */
/* */
/* Used genstrcpy instead of strcpy. */
/* */
/* Added before command execution callback */
/* function. */
/* */
/* Fixed RouteCommand return value. */
/* */
/* Added AwaitingInput flag. */
/* */
/* Added const qualifiers to remove C++ */
/* deprecation warnings. */
