+The BitBabbler is a hardware-based True Random Number generator
+(TRNG).  It is offered in both "White" and "Black" varieties that are
+functionally almost identical apart from throughput and cost.  This
+package installs the software necessary to control and perform basic
+health checks on connected BB devices.
+
+After installing the package, "groupadd bit-babbler", or adjust
+/etc/udev/rules.d/90-bit-babbler.rules to use an existing group (e.g.,
+wheel or adm) that will have permissions for the BB devices in your
+system.
+
+Typically, you'll probably want your BitBabbler device(s) to start
+feeding entropy to the kernel at boot.  Include these lines in
+/etc/rc.d/rc.local:
+
+# Start BitBabbler TRNG.
+if [ -x /etc/rc.d/rc.seedd ]; then
+   . /etc/rc.d/rc.seedd start
+fi
+
+It is also a good idea to stop your BB device from feeding entropy to
+the kernel before capturing the random number seed on shutdown/reboot.
+Put these lines in /etc/rc.d/rc.local_shutdown, which you'll need to
+create if it doesn't already exist:
+
+# Stop BitBabbler TRNG.
+if [ -x /etc/rc.d/rc.seedd ]; then
+   . /etc/rc.d/rc.seedd stop
+fi

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
