 This module provides a high-level interface for fetching data across
-the World-Wide Web.  In particular, the \code{urlopen()} function is
-similar to the built-in function \code{open()}, but accepts URLs
-(Universal Resource Locators) instead of filenames.  Some restrictions

+is similar to the built-in function \function{open()}, but accepts
+Universal Resource Locators (URLs) instead of filenames.  Some
+restrictions apply --- it can only open URLs for reading, and no seek

 It defines the following public functions:
 
 \begin{funcdesc}{urlopen}{url}
 Open a network object denoted by a URL for reading.  If the URL does
-not have a scheme identifier, or if it has \samp{file:} as its scheme

 identifier, this opens a local file; otherwise it opens a socket to a
 server somewhere on the network.  If the connection cannot be made, or
-if the server returns an error code, the \code{IOError} exception is
-raised.  If all went well, a file-like object is returned.  This
-supports the following methods: \code{read()}, \code{readline()},
-\code{readlines()}, \code{fileno()}, \code{close()} and \code{info()}.

+is raised.  If all went well, a file-like object is returned.  This
+supports the following methods: \method{read()}, \method{readline()},
+\method{readlines()}, \method{fileno()}, \method{close()} and
+\method{info()}.
 Except for the last one, these methods have the same interface as for
-file objects --- see the section on File Objects earlier in this
-manual.  (It's not a built-in file object, however, so it can't be
+file objects --- see section \ref{bltin-file-objects} in this
+manual.  (It is not a built-in file object, however, so it can't be
 used at those few places where a true built-in file object is
 required.)
 
-The \code{info()} method returns an instance of the class
-\code{mimetools.Message} containing the headers received from the server,
-if the protocol uses such headers (currently the only supported
-protocol that uses this is HTTP).  See the description of the
-\code{mimetools} module.

 \begin{funcdesc}{urlretrieve}{url}
 Copy a network object denoted by a URL to a local file, if necessary.
 If the URL points to a local file, or a valid cached copy of the
-object exists, the object is not copied.  Return a tuple (\var{filename},
-\var{headers}) where \var{filename} is the local file name under which
-the object can be found, and \var{headers} is either \code{None} (for
