 * The versions for TclX and TkX.  This is based on the versions of Tcl and Tk
 * that TclX was released against.  Its possible that TclX maybe running with
 * a different version of Tcl or Tk.  The basic versions are used for package
 * provide, the full versions as used for file names and include beta release
 * information and patch information.  The TCLX_DEBUG flag turns on asserts
 * etc.  Its an internal flag, however its normally true for alpha and beta
 * release and false for final releases, so we put the flag right by the 
 * version numbers in hopes that we will remember to change it.
 *
 * Examples:
 *   Release        _VERSION  _FULL_VERSION
 *   7.5.0           7.5.0     7.5.0
