NAME
       tkvars - Variables used or set by Tk

DESCRIPTION
       The following perl variables are either set or used by Tk at various
       times in its execution. (For a list of variables used by perl see perl-
       var.)

       $Tk::library
           This variable holds the file name for a directory containing the
           modules related to Tk.  These modules include an initialization
           file that is normally processed whenever a Tk application starts
           up, plus other files containing procedures that implement default
           behaviors for widgets.  The initial value of $Tk::library is set
           when Tk is added to an interpreter;  this is done by searching
           searching for a directory named Tk in the directory where the file
           Tk.pm, or the first directory Tk in @INC.

           The TK_LIBRARY environment variable used by Tcl/Tk is not supported
           by perl/Tk.  Please use @INC to change where modules are searched.

           Note: This is Tcl remnant. With perl it makes more sense to use
           @INC and %INC).

       $Tk::patchLevel
           Contains a decimal integer giving the current patch level for Tk.
           The patch level is incremented for each new release or patch, and
           it uniquely identifies an official version of Tk.

           Note: this is Tcl remnant. With perl it makes more sense to use
           $Tk::VERSION described below.

       $Tk::strictMotif
           This variable is set to zero by default.  If an application sets it
           to one, then Tk attempts to adhere as closely as possible to Motif
           look-and-feel standards.  For example, active elements such as but-
           tons and scrollbar sliders will not change color when the pointer
           passes over them.

       $Tk::VERSION
           The variable holds the current version number of the perl/Tk
           release in the form major.minor.  Major and minor are integers.

           The major version number shows on which Tcl/Tk release perl/Tk is
           based.  E.g., 402 means based on Tcls Tk 4.2.  (Patchlevel of Tcls
           Tk are not incorporated because perl/Tk tended  to be ``ahead'' of
           them on some fixes and behind on others.  The first digest of the
           major version number increases in any Tk release that includes
           changes that are not backward compatible (i.e. whenever existing
           perl/Tk applications and scripts may have to change to work with
           the new release).

           The minor version depends on perl/Tk only. It uses the 'even'='sta-
           ble', 'odd'='experimental' scheme that linux uses:

            .0xx  - inherently 'alpha'
            .1xx  - experimental 'beta'
            .2xx  - stable
            .3xx  - experimental
            .4xx  - stable
            ...

           The minor version number increases with each new release of Tk,
           except that it resets to zero whenever the major version number
           changes.

       $Tk::version
           The variable holds the current version number of the Tk library in
           the form major.minor.  Major and minor are integers.  The major
           version number increases in any Tk release that includes changes
           that are not backward compatible (i.e. whenever existing Tk appli-
           cations and scripts may have to change to work with the new
           release).  The minor version number increases with each new release
           of Tk, except that it resets to zero whenever the major version
           number changes.

           Note: this is Tcl remnant.  With perl it makes more sense to use
           $Tk::VERSION described above.
