 %description
 A small and lightweight parser library for ATA S.M.A.R.T. hard disk
 health monitoring.
 
+As the name suggests libatasmart only does ATA S.M.A.R.T.,
+there is no support for SCSI harddisks. SCSI S.M.A.R.T. is a
+very different system, support for it should be implemented in
+a separate library "libscsismart" if there should ever be
+demand for it.
+
+This library is supposed to be lean and small and thus
+supports only a subset of the S.M.A.R.T. functionality.
+However, I claim that it implements the relevant part of it.
+If you need full control over all S.M.A.R.T. functionality of
+your hardware please refer to Buce Allen's smartmontools.
