       Tcl_Interp   *interp	       (in)	 Interpreter  to use for error reporting, or NULL
						 if no error reporting is desired.

       CONST char   *resourceName      (in)	 Name of TEXT resource to source, NULL if  number
						 should be used.

       int	    resourceNumber     (in)	 Resource id of source.

       Handle	    resource	       (in)	 Handle to TEXT resource.

       long	    resourceType       (in)	 Type of resource to load.

       CONST char   *resFileRef        (in)	 Registered  resource  file  reference,  NULL  if
						 searching all open resource files.

       int	    *releaseIt	       (out)	 Should we release this resource when done.

       int	    newOSType	       (in)	 Int used to initialize the new object or set the
						 object's value.

       Tcl_Obj	    *objPtr	       (in)	 Object whose internal representation  is  to  be
						 set or retrieved.

       osTypePtr    out 			 Place to store the resulting integer.

       Tcl_MacConvertEventPtr	       procPtr(in)
						 Reference  to	the  new  function  to handle all
						 incoming Mac events.


       The described routines are used to implement the Macintosh specific resource  command  and
       the  Mac specific notifier.. They manipulate or use Macintosh resources and provide admin-
       istration for open resource file references.

       Tcl_MacEvalResource extends the source command to Macintosh  resources.	 It  sources  Tcl
       code  from  a Text resource.  Currently only sources the resource by name, file IDs may be
       supported at a later date.

       Tcl_MacConvertTextResource converts a TEXT resource into a Tcl suitable string. It mallocs
       the  returned  memory,  converts  ``\r'' to ``\n'', and appends a null. The caller has the
       responsibility for freeing the memory.

       Tcl_MacFindResource provides a higher level interface for loading resources. It is used by
       resource read.

       Tcl_NewOSTypeObj  is  used  to  create a new resource name type object. The object type is

       Tcl_SetOSTypeObj modifies an object to be a resource type and to have the  specified  long

       Tcl_GetOSTypeFromObj attempts to return an int from the Tcl object "objPtr". If the object
       is not already an int, an attempt will be made to convert it to one.

       Tcl_MacSetEventProc sets the event handling procedure for the application.  This  function
       will  be  passed  all  incoming Mac events.  This function usually controls the console or
       some other entity like Tk.

       Resource types are 4-byte values used by the macintosh resource facility to tag	parts  of
       the  resource  fork  in a file so that the OS knows how to handle them. As all 4 bytes are
       restricted to printable characters such a type can be interpreted as a 4 character  string
