NAME
       tkvars - Variables used or set by Tk


DESCRIPTION
       The following STk variables are either set or used by Tk at various
       times in its execution:

       *tk-patch-level*
              Contains a string which represent 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.

       *tk-strict-motif*
              This variable is set to #f by default.  If an application sets
              it to a true value, then Tk attempts to adhere as closely as
              possible to Motif look-and-feel standards.  For example, active
              elements such as buttons and scrollbar sliders will not change
              color when the pointer passes over them.

       *tk-version*   Tk sets this variable in the interpreter for each
                      application.  The value of this variable is a string
                      which 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 applications 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.
