but it also says:

  Try `heatbugs --help' or `heatbugs --usage' for more information.

So, if you do that:

  ./heatbugs --help

You get:

  Usage: heatbugs [OPTION...]

    -s, --varyseed             Run with a random seed
  [descriptions of other options]

Note that the varyseed option has been renamed to have two forms:
a short form of `-s' and a long form of `--varyseed' (if you are
wondering why the short form isn't `-v', it's because `-v' is
typically reserved for a `verbose' mode of use, for printing
diagnostics and the like).

This change was a part of a larger change to systematically and
deal with command-line arguments in an extensible way; it's how most GNU
programs parse command-line options.
