SYNOPSIS
       tkerror message

DESCRIPTION
       Note: as of Tk 4.1 the tkerror command has been renamed to bgerror because the event loop (which is what usually invokes it) is now part of
       Tcl.  For backward compatibility the bgerror provided by the current Tk version still tries to call tkerror if there is	one  (or  an  auto
       loadable  one),	so  old  script  defining  that  error handler should still work, but you should anyhow modify your scripts to use bgerror
       instead of tkerror because that support for the old name might vanish in the near future. If that call fails, bgerror posts a dialog  show-
       ing  the  error and offering to see the stack trace to the user. If you want your own error management you should directly override bgerror
       instead of tkerror.  Documentation for bgerror is available as part of Tcl's documentation.
