Added documentation for inet_aton() and inet_ntoa(), from Ben
Gertzfield <che@debian.org> (with minor changes).
(Should have been here instead of in the branch in the first place,
since these weren't in for the 1.5.2 release.)

+\begin{funcdesc}{inet_aton}{ip_string}
+Convert an IP address from dotted-quad string format
+(e.g.\ '123.45.67.89') to 32-bit packed binary format, as a string four
+characters in length.
+
+Useful when conversing with a program that uses the standard C library
+and needs objects of type \ctype{struct in_addr}, which is the C type
+for the 32-bit packed binary this function returns.
+
+If the IP address string passed to this function is invalid,
+\exception{socket.error} will be raised. Note that exactly what is
+valid depends on the underlying C implementation of
+\cfunction{inet_aton()}.

+\begin{funcdesc}{inet_ntoa}{packed_ip}

+length) to its standard dotted-quad string representation
+(e.g. '123.45.67.89').

+Useful when conversing with a program that uses the standard C library

\begin{datadesc}{SocketType}
This is a Python type object that represents the socket object type.
It is the same as \code{type(socket(...))}.
