+     "Scanbd stands for scanner button daemon.  It regulary polls scanners for
+pressed buttons, function knob changes, or other events such as (un)plugging
+the scanner or inserting and removing paper.  Then it performs the desired
+action(s) such as saving, copying, or e-mailing the image.
+
+Actions can be fully customised through scripts, based on any combination of
+switch or knob settings.  Events are also signaled over D-Bus and scans can
+even be triggered over D-Bus from foreign applications.
+
+Scanbd talks to scanners through the @acronym{SANE, Scanner Access Now Easy}
+back-end library.  This means that it supports almost all existing scanners,
+provided the driver also exposes the buttons.")
