+ \begin{datadesc}{_urlopener}
+ The public functions \function{urlopen()} and
+ \function{urlretrieve()} create an instance of the
+ \class{FancyURLopener} class and use it to perform their requested
+ actions. To override this functionality, programmers can create a
+ subclass of \class{URLopener} or \class{FancyURLopener}, then assign
+ that an instance of that class to the
+ \code{urllib._urlopener} variable before calling the desired function.
+ For example, applications may want to specify a different
+ \mailheader{User-Agent} header than \class{URLopener} defines. This
+ can be accomplished with the following code:
+
+ \begin{verbatim}
+ import urllib
