-* GNU m4
+* md5sum (GNU textutils; alternatively, Colin Plumb's, as shipped with
+          Debian in the `dpkg' package) - used during build only
+* GNU m4 (only if you need to change the m4 input)
 * GNU make
-* GNU flex
+* GNU flex [fixme: should ship the output]
 * GCC is preferred but other compilers ought to work (though
   no portability testing has yet been done).  ANSI C only.
   ints must be at least 32 bits.
-* A sensible /bin/cat which notices write errors (ie not
-  SunOS4, BSD 4.3, or many others.)
+* A sensible `cat' which notices write errors (ie not SunOS4, BSD 4.3,
+  or many others.  GNU textutils has one.  NB that this `cat' is used
+  at runtime and must be first on the system default PATH, so probably
+  in /bin.)
