 This directory contains C sourcfiles intended to test deheader, and
 a check against which to compare the output.
+
+Many of these examples are takem from the Single Unix Standard's list
+of section 2 and 3 entry points.  I don't explicitly test anything in
+SuS with a structure- or pointer-to-structure type argument; that will
+fail as it should on any modern compiler because the struct is neither
+defined nor the derived pointer type forward-declared with a stup.
+
+SuS things excluded by this criterion:
+
+aio.h  - aio_* entry points for asynchronous input and output
+time.h - asctime() and asctime_r()
