  26.           This procedure is typically invoked when a Tcl error  occurs
  27.           during  ``background  processing''  such  as executing a Tcl
  28.           command  in  response  to  a  button  press  or  menu  entry
  29.           invocation.   When such an error occurs, the error condition
  30.           is reported to Tk or to a widget or some other C  code,  and
  31.           there is not usually any obvious way for that code to report
  32.           the error to the  user.   In  these  cases  the  code  calls
  33.           TTTTkkkk____BBBBaaaacccckkkkggggrrrroooouuuunnnnddddEEEErrrrrrrroooorrrr  with  an _i_n_t_e_r_p argument identifying the
  34.           interpreter in which the error occurred.  TTTTkkkk____BBBBaaaacccckkkkggggrrrroooouuuunnnnddddEEEErrrrrrrroooorrrr
  35.           attempts  to  invoke  the  ttttkkkkeeeerrrrrrrroooorrrr Tcl command to report the
  36.           error in an application-specific  fashion.   If  no  ttttkkkkeeeerrrrrrrroooorrrr
  37.           command  exists,  or  if it returns with an error condition,
  38.           then TTTTkkkk____BBBBaaaacccckkkkggggrrrroooouuuunnnnddddEEEErrrrrrrroooorrrr reports the error itself by printing
  39.           a message on the standard error file.
