+ (description
+ "The canonical way to determine the size of a file in bytes, using
Common Lisp,
+is to open the file with an element type of (unsigned-byte 8) and then
+calculate the length of the stream. This is less than ideal. In most cases
+it is better to get the size of the file from its metadata, using a system
+call.
+
+This library exports a single function, file-size-in-octets. It returns the
+size of a file in bytes, using system calls when possible.")
