vips [options] [command] [command-options] [command-args]

DESCRIPTION
vips(1) is the VIPS universal main program. You can use it to run any VIPS operation from the command line, to query the VIPS function database, and to maintain parts of the VIPS library. To run a VIPS function, the first argument should be the name of the function and following arguments should be the function parameters. For example:
  $ vips im_invert lena.v lena2.v

  where:
    left :: VipsImage (input)
