+All interfaces (data types and functions) of the library are defined
+in the header file `fko.h'.  You must include this in all programs
+using the library, either directly or through some other header file,
+like this:
+
+@example
+#include <fko.h>
+@end example
+
+The name space of @acronym{FKO} is @code{fko_*} for function names and
+data types and @code{FKO_*} for other symbols. Other symbols internal to
+@acronym{FKO} may take the form @code{_fko_*} and @code{_FKO_*}.
