  13 # This script passes filename and line number of a latex file to the lyxpipe
  14 # of a running instance of LyX. If the filename is an absolute path pointing
  15 # to an already existing latex file in the temp dir (produced by a preview,
  16 # for example), LyX will jump to the corresponding line in the .lyx file.
  17 # It may also be invoked by a viewer for performing a reverse DVI/PDF search.
