 '\"	and indent is equivalent to second arg of .IP (shouldn't ever be
 '\"	needed;  use .AS below instead)
 '\"
 '\" .AS ?type? ?name?
 '\"	Give maximum sizes of arguments for setting tab stops.  Type and

 '\"	to .AP later.  If args are omitted, default tab stops are used.

 .sp
 CONST char *
 \fBTk_InitStubs\fR(\fIinterp, version, exact\fR)
 .SH ARGUMENTS
 .AS Tcl_Interp *interp in

 Tcl interpreter handle.
 .AP char *version in
 A version string consisting of one or more decimal numbers
 separated by dots.
 .AP int exact in
 Non-zero means that only the particular Tk version specified by
 \fIversion\fR is acceptable.
 Zero means that versions newer than \fIversion\fR are also
 acceptable as long as they have the same major version number
 as \fIversion\fR.
 .BE
 .SH INTRODUCTION
 .PP
 The Tcl stubs mechanism defines a way to dynamically bind
 extensions to a particular Tcl implementation at run time.
 the stubs mechanism requires no changes to applications
 incoporating Tcl/Tk interpreters.  Only developers creating
 C-based Tcl/Tk extensions need to take steps to use the
 stubs mechanism with their extensions.
 See the \fBTcl_InitStubs\fR page for more information.
 .PP
 Enabling the stubs mechanism for a Tcl/Tk extension requires the following
 steps:
 .IP 1) 5
 Call \fBTcl_InitStubs\fR in the extension before calling any other
 Tcl functions.
 .IP 2) 5
 Call \fBTk_InitStubs\fR if the extension before calling any other
 Tk functions.
 .IP 2) 5
 Define the USE_TCL_STUBS symbol.  Typically, you would include the
 -DUSE_TCL_STUBS flag when compiling the extension.
 .IP 3) 5
 Link the extension with the Tcl and Tk stubs libraries instead of
 the standard Tcl and Tk libraries.  On Unix platforms, the library
 names are \fIlibtclstub8.4.a\fR and \fIlibtkstub8.4.a\fR; on Windows
 platforms, the library names are \fItclstub84.lib\fR and \fItkstub84.lib\fR
 (adjust names with appropriate version number).
 .SH DESCRIPTION
 \fBTk_InitStubs\fR attempts to initialize the Tk stub table pointers
 and ensure that the correct version of Tk is loaded.  In addition
 to an interpreter handle, it accepts as arguments a version number
 and a Boolean flag indicating whether the extension requires
 an exact version match or not.  If \fIexact\fR is 0, then the
 extension is indicating that newer versions of Tk are acceptable
 as long as they have the same major version number as \fIversion\fR;
 non-zero means that only the specified \fIversion\fR is acceptable.
 \fBTcl_InitStubs\fR returns a string containing the actual version
 of Tk satisfying the request, or NULL if the Tk version is not
 acceptable, does not support the stubs mechansim, or any other
 error condition occurred.
