+FreeBSD Developer Support
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The --freebsd-option provides a tool you can set special kernel options. This
+is a developer tool and should only be used if you are familiar with the
+internals of the FreeBSD kernel and what these options do.
+
+The options are listed in:
+
+ https://github.com/freebsd/freebsd/blob/master/sys/conf/NOTES
+
+An example to turn on a verbose kernel boot, verbose sysinit and bus debugging
+configure with:
+
+ --freebsd-options=bootverbose,verbose_sysinit,bus_debug
+
+The LibBSD waf support splits the options and converts them to uppercase and
+adds them -D options on the compiler command line.
