<h3>Site Management Tools</h3>
<p>The following Python tools are used to manage Web sites. They implement several functions that simplify the daily tasks performed by webmasters, such as dead link checking, and object publishing.</p>
<H4>WebDAV/PyDAV</H4>
<P><I>WebDAV (World Wide Web Distributed Authoring and Versioning)</i> is a set of extensions to the HTTP/1.1 protocol, which allows users to collaboratively edit, manage, and update files safely on remote Web servers. It was developed by the WebDAV working group of the <a naME="idx1073746450"></A><A name="idx1073746451"></A>Internet Engineering Task Force (IETF).</P>
<P>WebDAV provides a standard infrastructure for asynchronous collaborative authoring across the Internet in order to turn the Web into a collaborative environment.</P>
<p>WebDAV has the following core features: Metadata management, Name space management, Collections, Overwrite prevention, Version management, Access Control, and Locking (concurrency control).</p>
<p>For more information about WebDAV, check out its Web site at</p>
<p><a target="_blank" href="http://www.webdav.org">http://www.webdav.org</a><a naMe="idx1073746452"></a><A namE="idx1073746453"></a><a naMe="idx1073746454"></a><a NAME="idx1073746455"></a></p>
<p>PyDAV is a WebDAV (also known as DAV) server implemented in Python. Check out its Web site at the following address:</p>
<P>
<A TArget="_blank" HREF="http://sandbox.xerox.com/webdav/">http://sandbox.xerox.com/webdav/</a><a naME="idx1073746456"></A><A name="idx1073746457"></a><a name="idx1073746458"></a><a name="idx1073746459"></a><a naMe="idx1073746460"></a><A namE="idx1073746461"></a><a naMe="idx1073746462"></a><a NAME="idx1073746463"></a><a naME="idx1073746464"></A><A name="idx1073746465"></A><A NAme="idx1073746466"></a><a NAME="idx1073746467"></a><a name="idx1073746468"></a><a name="idx1073746469"></a></p>
<h4>Zebra</h4>
<p>Zebra is an XML-based preprocessing language that offers a compact syntax for expressing common Web design patterns. Similar to Zope, Zebra is a templating system that is able to preprocess Python code. Therefore, developers don't need to stick to the details of the language before starting a nice design. For more information, check out the following site:</p>
<p><a TarGet="_blank" hRef="http://zebra.sourceforge.net/">http://zebra.sourceforge.net/</a><a Name="idx1073746470"></A><A NAme="idx1073746471"></a><a NAME="idx1073746472"></a><a naME="idx1073746473"></A></P>
<h4><tt cLASS="monofont">httpd_log</tt></h4>
<p>The HTTPD logfile reporting tool (<tt class="monofont">httpd_log</tt>) is a graphical Web statistics tool that analyzes HTTP log files and generates a page of summary information, complete with statistical graphs. Richard Jones developed this tool.</p>
<p>You'd better check out the new release 4.0b1 because it uses the more accurate <a name="idx1073746474"></A><a nAme="idx1073746475"></a><Tt claSs="monofont">PIL</tt> module, instead of using the old <A NAMe="idx1073746476"></a><a nAME="idx1073746477"></A><tt clASS="monofont">GD</Tt> graphic module. Although the release 3.0 is very stable, the graphing provided by the new release is more accurate.</p>
<p>Keep in mind that you need to install the PIL module (<tT CLAss="monofont">PILGraph-0.1a7.tar.gz</tt>) in order to use the release 4.0b1. For more information, check out</p>
<p><a target="_blank" href="http://starship.python.net/crew/richard/httpd_log/">http://starship.python.net/crew/richard/httpd_log/</a><a nAme="idx1073746478"></A><a naMe="idx1073746479"></a><a nAme="idx1073746480"></a><A NAMe="idx1073746481"></a></p>
<h4>Linbot</H4>
<P>Linbot is a site management tool that analyzes a site and allows the user to view a site map, check for broken internal and external links, missing images, and list other problems that were found. It downloads each page from the Web site, and parses its contents in order to collect all the site's information. Linbot is extensible, so new tests can be added by writing some Python code.</P>
<P>Some of the things that Webmasters can do periodically and without user intervention when using Linbot are listed as follows:<a namE="idx1073746482"></A><A Name="idx1073746483"></a><A NAMe="idx1073746484"></a><a name="idx1073746485"></a><a name="idx1073746486"></a><a name="idx1073746487"></a><A naMe="idx1073746488"></a><a Name="idx1073746489"></a><A namE="idx1073746490"></A><A Name="idx1073746491"></a><A NAMe="idx1073746492"></a><a nAME="idx1073746493"></A><a namE="idx1073746494"></A></P>

<h4>Python-Friendly Internet Solution Providers (ISPs)</H4>
<p>The Web site "Python-friendly ISPs" lists Web site providers that support the execution of CGI scripts written in Python. These lists are separated into some specific categories:</p>
<Ul>
<li><P>Python Installed System-Wide</p>
</li>
<lI><p>User May Install Python in Own Directories</p>
</lI>
<LI><P>Providers with No Python Installed</p>
</li>
<lI><P>Other Providers (Python Support Unknown)</P>
</Li>
</ul>
<p>The address is <A TARget="_blank" hREF="http://www.corrt.com/info/pyisp-list.html">http://www.corrt.com/info/pyisp-list.html</A><a name="idx1073746499"></a><a name="idx1073746500"></a><a name="idx1073746501"></a><a nAme="idx1073746502"></A><a naMe="idx1073746503"></a><a nAme="idx1073746504"></a><A NAMe="idx1073746505"></a><a nAME="idx1073746506"></A><a namE="idx1073746507"></A><A Name="idx1073746508"></a><A NAMe="idx1073746509"></a></p>
<h4><tt class="monofont">mxCGIPython</tt></h4>
<p>Instead of looking for an ISP that supports Python, you might be interested in the <tt claSs="monofont">mxCGIPython</tT> tool, which helps you install Python on your ISP when your ISP either <i>won't</i> or <i>can't.</I> Marc-Andre Lemburg has put together a small Zip file, which contains all necessary <tt clAss="monofont">setup</tT> and <TT Class="monofont">config</TT> files. For more information, check out the following:</P>
<P><a tarGET="_blank" Href="http://starship.python.net/~lemburg/mxCGIPython.html">http://starship.python.net/~lemburg/mxCGIPython.html</a>
</P>
<H4><TT class="monofont">HTMLgen</tt></h4>
<p>If you need a module to help you generate HTML, you should check out <tt class="monofont">HTMLgen,</tt> written by Robin Friedrich. It's a class library of objects corresponding to all the HTML 3.2 markup tags. It's used when you are writing in Python and want to synthesize HTML pages for generating a Web, for CGI forms, and so on. The following lines are some examples of using <tt ClaSs="monofont">HTMLgen:</tt></P>
<pre>
>>> print H(1, "Welcome to Python World")
<H1>Welcome to Python World</H1>
>>> print A("http://www.python.org/", "Python Web site")
<A HREF="http://www.python.org/">Python Web site</A>
</pRe>
<p>HTMLgen is available for download at:</p>
<P><A TArget="_blank" HREF="http://starship.python.net/crew/friedrich/HTMLgen/html/main.html">http://starship.python.net/crew/friedrich/HTMLgen/html/main.html</a></p>
<h4>Document Template</h4>
<P>When talking about generating HTML code, it might also be useful to consider <TT Class="monofont">DocumentTemplate,</TT> which offers clear separation between Python code and HTML code. <TT class="monofont">DocumentTemplate</tt> is part of the Zope objects publishing system, but it can also be used independently. For more information, check out the following:</p>
<p>
<a target="_blank" href="http:/www.digicool.com/">http:/www.digicool.com/</A><a nAme="idx1073746510"></a><A name="idx1073746511"></A><a naME="idx1073746512"></A><A name="idx1073746513"></A></P>
<H4>Persistent CGI</H4>
<p>Persistent CGI architecture provides a reasonably high-performance, transparent method of publishing objects as long running processes via the World Wide Web (WWW). The current alternatives to CGI that allow the publishing of long-running processes, such as FastCGI and ILU, have some level of Web server and platform dependencies. Persistent CGI allows a long running process to be published via the WWW on any server that supports CGI, and requires no specific support in the published application.<a naME="idx1073746514"></A><A name="idx1073746515"></A><A NAme="idx1073746516"></a><a name="idx1073746517"></a><a name="idx1073746518"></a><a name="idx1073746519"></A><a nAme="idx1073746520"></a><A name="idx1073746521"></A><a naME="idx1073746522"></A></P>
<div cLASS="note"><p claSS="notetitle"><B>Note</B></p><p>
<p>The latest version of Persistent CGI is bundled with the Zope software:</p>
