179 This driver can spew a whole lot of debugging output at you. If you
180 need maximum performance, you should disable the DEBUG define. To
181 aid in debugging in the field, I'm leaving the compile-time debug
182 features enabled, and disable them "runtime". That allows me to
183 instruct people with problems to enable debugging without requiring
