+    (description
+     "@code{Modprobed-db} is a useful utility for users wishing to build a
+minimal kernel via a @code{make localmodconfig}.  In a nutshell, this make
+target creates a config based on the current config and a list of modules you
+define (@code{modprobed-db} keeps for you).  It then disables any module
+option that is not needed thus not building hundreds/potentially thousands of
+extraneous modules.  This results in a system-specific, streamlined kernel
+package and footprint as well as reduced compilation times.
+
+@code{Modprobed-db} simply logs every module ever probed on the target system
+to a text-based database (@code{$XDG_CONFIG_HOME/modprobed-db}) which can be
+read directly by @code{make localmodconfig} as described above.")
