Tools/scripts directory. If you've already been using the PyBSDDB
package, importing it as \module{bsddb3}, you will have to change your

\item The new \module{bz2} module is an interface to the bz2 data
compression library. bz2 usually produces output that's smaller than
the compressed output from the \module{zlib} module, meaning that it
compresses data more highly. (Contributed by Gustavo Niemeyer.)

an extra constructor argument named \var{depends} for listing

\item The DOM implementation
in \module{xml.dom.minidom} can now generate XML output in a
particular encoding by providing an optional encoding argument to
the \method{toxml()} and \method{toprettyxml()} methods of DOM nodes.
item The \module{Tix} module has received various bug fixes and
updates for the current version of the Tix package.

\item The new \module{DocXMLRPCServer} module allows writing
self-documenting XML-RPC servers. Run it in demo mode (as a program)
to see it in action. Pointing the Web browser to the RPC server
produces pydoc-style documentation; pointing xmlrpclib to the
server allows invoking the actual methods.

\item Support for internationalized domain names (RFCs 3454, 3490,
3491, and 3492) has been added. The ``idna'' encoding can be used
to convert between a Unicode domain name and the ASCII-compatible
encoding (ACE).
encoding (ACE) of that name.
\begin{alltt}
>>> u"www.Alliancefran\c{c}aise.nu".encode("idna")
'www.xn--alliancefranaise-npb.nu'
\end{alltt}
In addition, the \module{socket} has been extended to transparently
convert Unicode hostnames to the ACE before passing them to the C
library. In turn, modules that pass hostnames ``through'' (such as
\module{httplib}, \module{ftplib}) also support Unicode host names
(httplib also sends ACE Host: headers). \module{urllib} supports
Unicode URLs with non-ASCII host names as long as the \code{path} part
of the URL is ASCII only.
The \module{socket} module has also been extended to transparently
convert Unicode hostnames to the ACE version before passing them to
the C library. Modules that deal with hostnames such as
\module{httplib} and \module{ftplib}) also support Unicode host names;
\module{httplib} also sends HTTP \samp{Host} headers using the ACE
version of the domain name. \module{urllib} supports Unicode URLs
with non-ASCII host names as long as the \code{path} part of the URL
is ASCII only.
To implement this change, the module \module{stringprep}, the tool
\code{mkstringprep} and the \code{punycode} encoding have been added.
