+    (description
+     "When dealing with network protocols and file formats, it's common to
+have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned
+flavors.  Common Lisp sort of supports this by specifying :element-type for
+streams, but that facility is underspecified and there's nothing similar for
+read/write from octet vectors.  What most people wind up doing is rolling their
+own small facility for their particular needs and calling it a day.
+
+This library attempts to be comprehensive and centralize such
+facilities.  Functions to read 16-, 32-, and 64-bit quantities from octet
+vectors in signed or unsigned flavors are provided; these functions are also
+SETFable.  Since it's sometimes desirable to read/write directly from streams,
+functions for doing so are also provided.  On some implementations,
+reading/writing IEEE singles/doubles (i.e. single-float and double-float) will
+also be supported.")
