${title}
Depending on the name of the script `vpe' works in four modes:

* [vpe] Syntax: vpe <pdf file>[.pdf]
  The pdf file is scanned for actions created by VTeX,
  that start an editor with the source file at the
  specified line under Windows.
  A symbol link is made from the source file name
  extended by the extension `.vpe' to this script.
  The line number is encoded in the path and the
  action is changed to start this script.

* [sty] Internal for vpe.sty:
  Syntax: vpe --sty [--progname=...] <latex file> <vpe file>

* [system] Internal for vpe.sty:
  Syntax: vpe --system <vpe file>

* [launch] Syntax: <source file name>.vpe
  The script decodes the line number in the path of
  the source file name and starts an editor with
  this file at that line number.

Options:
  --help:     print usage.
  --verbose:  print additional informations during running.
  --force:    force symbol links
  --delete:   delete symbol links
  --sty:      internal for `vpe.sty' (get absolute file name and lines)
  --system:   internal for `vpe.sty' (get system info linux or win)
  --progname: latex, pdflatex, elatex, pdfelatex
