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