Usage: Create a symlink midori-<CMD>, or run 'midori-dev <CMD>'
where CMD can be
  bzr:  run the current bzr version
  gdb:  open the last core dump in gdb
  save: saves relevant information about the last crash
        so that it can be analyzed later
  pull: pulls the latest updates from the repository
