  21 # With this script you can run libvirt programs without needing to
  22 # install them first.  You just have to do for example:
  23 #
  24 #   ./run ./tools/virsh [args ...]
  25 #
  26 # If you are already in the tools/ subdirectory, then the following
  27 # command will also work:
  28 #
  29 #   ../run ./virsh [...]
  30 #
  31 # You can also run the C programs under valgrind like this:
  32 #
  33 #   ./run valgrind [valgrind opts...] ./program
  34 #
  35 # or under gdb:
  36 #
  37 #   ./run gdb --args ./program
  38 #
  39 # This also works with sudo (eg. if you need root access for libvirt):
  40 #
  41 #   sudo ./run ./tools/virsh list --all
