  Output written on emacs-lisp-intro.dvi (272 pages, 986064 bytes).
  Transcript written on emacs-lisp-intro.log.
  /home/e/eliz/bin/texi2dvi: etex exited with bad status, quitting. <<<<<<<<<

Does anyone have any idea what causes this?  The only messages that
could mean trouble are:

  ./emacs-lisp-intro.texi:9527: epsf.tex not found, images will be ignored.
  @image ...f.tex not found, images will be ignored}
                                                    @global @warnednoepsftrue 
...
  <argument> @hfil @ignorespaces @image {cons-1}
                                                @unskip @hfil
  @centersub ...enalty @fi @line {@kern @leftskip #1
                                                    @kern @rightskip }
  @\center ...{@hfil @ignorespaces #1@unskip @hfil }
                                                    @let @centersub @relax
  l.9527 @center @image{cons-1}

Is that the reason? that epsf.tex is missing?
