Actually, this package provides a library that uses libusb to interface
with the HackRF software defined radio. Shall I rewrite the synopsis and
description as follows, replacing "driver" with "library"? Or, should I
say "userspace driver" instead of "library"?

synopsis:

Interface library for the HackRF software defined radio

description:

@code{hackrf} provides a library to interface with HackRF, a general
purpose software defined radio.
