+   AR File - Handle an 'AR' archive
+   
+   This is a reader for the usual 4.4 BSD AR format. It allows raw
+   stream access to a single member at a time. Basically all this class
+   provides is header parsing and verification. It is up to the client
+   to correctly make use of the stream start/stop points.
