       Tcl_Interp *interp (in/out)			    The interpreter in which  the  names-
							    pace  exists  and  where name lookups
							    are  performed.  Also   where   error
							    result messages are written.

       const char *name (in)				    The  name of the namespace or command
							    to be created or accessed.

       ClientData clientData (in)			    A context pointer by the  creator  of
							    the  namespace.   Not  interpreted by
							    Tcl at all.

       Tcl_NamespaceDeleteProc *deleteProc (in) 	    A pointer to function  to  call  when
							    the  namespace is deleted, or NULL if
							    no such callback is to be performed.

       Tcl_Namespace *nsPtr (in)			    The namespace to be  manipulated,  or
							    NULL (for other than Tcl_DeleteNames-
							    pace)  to  manipulate   the   current

       Tcl_Obj *objPtr (out)				    A  reference to an unshared object to
							    which the  function  output  will  be

       const char *pattern (in) 			    The     glob-style	  pattern    (see
							    Tcl_StringMatch) that  describes  the
							    commands to be imported or exported.

       int resetListFirst (in)				    Whether  the  list of export patterns
							    should be  reset  before  adding  the
							    current pattern to it.

       int allowOverwrite (in)				    Whether  new commands created by this
							    import action can overwrite  existing

       Tcl_Namespace *contextNsPtr (in) 		    The location in the namespace hierar-
							    chy where the search for a	namespace
							    or	command should be conducted rela-
							    tive to when the search term  is  not
							    rooted at the global namespace.  NULL
							    indicates the current namespace.

       int flags (in)					    OR-ed combination of bits controlling
							    how  the  search  is to be performed.
							    The following  flags  are  supported:
							    TCL_GLOBAL_ONLY  (indicates  that the
							    search is always to be conducted rel-
							    ative   to	 the  global  namespace),
							    TCL_NAMESPACE_ONLY	   (just      for
							    Tcl_FindCommand;  indicates  that the
							    search is always to be conducted rel-
							    ative  to the context namespace), and
							    TCL_LEAVE_ERR_MSG (indicates that  an
							    error  message  should be left in the
							    interpreter if the search fails.)

       Tcl_Obj *handlerPtr (in) 			    A script fragment to be installed  as
							    the  unknown  command handler for the
							    namespace, or NULL to reset the  han-
							    dler to its default.

       Namespaces  are	hierarchic naming contexts that can contain commands and variables.  They
       also maintain a list of patterns that describes what commands are exported, and can import
       commands  that have been exported by other namespaces.  Namespaces can also be manipulated
       through the Tcl command namespace.

       The Tcl_Namespace structure encapsulates a namespace, and is guaranteed to have	the  fol-
       lowing  fields  in  it: name (the local name of the namespace, with no namespace separator
       characters in it, with empty denoting the global namespace), fullName (the fully specified
       name  of  the  namespace),  clientData,	deleteProc  (the  values specified in the call to
       Tcl_CreateNamespace), and parentPtr (a pointer to the containing namespace,  or	NULL  for
       the global namespace.)

       Tcl_CreateNamespace  creates a new namespace.  The deleteProc will have the following type
	      typedef void (Tcl_NamespaceDeleteProc) (ClientData clientData);

       Tcl_DeleteNamespace deletes a namespace.

       Tcl_AppendExportList retrieves the export patterns for a  namespace  given  namespace  and
       appends them (as list items) to objPtr.

       Tcl_Export sets and appends to the export patterns for a namespace.  Patterns are appended
       unless the resetListFirst flag is true.

       Tcl_Import imports commands matching a pattern into a namespace.  Note  that  the  pattern
       must  include the name of the namespace to import from.	This function returns an error if
       an attempt to import a command over an existing command is made, unless the allowOverwrite
       flag has been set.

       Tcl_ForgetImport removes imports matching a pattern.

       Tcl_GetCurrentNamespace returns the current namespace for an interpreter.

       Tcl_GetGlobalNamespace returns the global namespace for an interpreter.

       Tcl_FindNamespace  searches for a namespace named name within the context of the namespace
       contextNsPtr.  If the namespace cannot be found, NULL is returned.

       Tcl_FindCommand searches for a command named name within the context of the namespace con-
       textNsPtr.  If the command cannot be found, NULL is returned.

       Tcl_GetNamespaceUnknownHandler  returns	the unknown command handler for the namespace, or
       NULL if none is set.

       Tcl_SetNamespaceUnknownHandler sets the unknown command handler for the namespace. If han-
       dlerPtr is NULL, then the handler is reset to its default.
