#
# This Makefile is meant to be included by packages that require an
# implementation of the former libusb (still found in devel/libusb). The
# original implementation can be chosen by setting LIBUSB_TYPE to "native".
#
# The alternative implementation libusb-compat (found in devel/libusb-compat)
# wraps libusb1 (in devel/libusb1). This implementation can be chosen by setting
# LIBUSB_TYPE to "compat". On NetBSD, it has the advantage of not requiring root
# privileges to locate and use USB devices without a kernel driver.
#
# User-settable variables:
#
# LIBUSB_TYPE
#	The name of the libusb implementation to default to, native or compat.
