--------
Just type 'make' and 'make install'. If on FreeBSD, for now you have to
-specify the FreeBSD Makefile with -f, eg:
+specify the FreeBSD Makefile with -f and use gmake (not make), eg:
-$ make -f Makefile.Freebsd && make -f Makefile.FreeBSD install
+$ gmake -f Makefile.Freebsd && gmake -f Makefile.FreeBSD install
Likewise with OpenSolaris, use the Makefile.solaris to compile there.
-This might change in the future if I opt for an autoconf type setup.
+The OpenSolaris make should work fine. This might change in the
+future if I opt for an autoconf type setup.

has a null io engine, which is mainly used for testing
verify=x If 'x' == md5, use md5 for verifies. If 'x' == crc32,
use crc32 for verifies. md5 is 'safer', but crc32 is
a lot faster. Only makes sense for writing to a file.
