Usage: ./bootstrap [--configure] [--prefix PATH] [-- CONFIGURE_ARGS...]

Regenerates Autotools files using autoreconf.
By default this does not run ./configure.

Options:
  --configure      Run ./configure after autoreconf.
  --prefix PATH    Prefix used when --configure is set.
  --help           Show this help.

Backward compatibility:
  A single positional argument is treated as --prefix PATH and implies --configure.
