-very high-performance, stable, and feature rich system authored by Michael Teele 
-with lots of users. Written in C, it&#39;s an amazingly efficient system that can run on very underpowered boxes. In exchange, it&#39;s huge

 <h2>11.1 Goals</h2>
 <p>The primary goals of <span class="code">weewx </span>are:</p>
 <ul>
-	<li>Architectural simplicity. No semaphores, no named pipes, no 
-	inter-process communications, no complex 
-	multi-threading to manage. </li>
-	<li>One code base. The same code base should be used 
-	for all platforms and any combination of features. 
-	Ample configuration options should be provided so the user doesn&#39;t feel 
-	tempted to start hacking code. At worse, the user may have to subclass, 
-	which is much easier to port to newer versions of the code base.</li>
-	<li>Minimal reliance on external packages, so the user doesn&#39;t have to go 
-	chase them down all over the Web.</li>
-	<li>&quot;Fast enough.&quot; In any design decision, architectural simplicity trumps speed. </li>
-	<li>Support only the Davis VantagePro2 initially (that&#39;s what I have), but 
-	make no architectural decisions that lock out other stations.</li>
-	<li>As &quot;pythonic&quot; as I know how to make it. I&#39;m a beginner Python 
-	programmer with two decades of experience in C++. I tried hard to not make 
-	the code base look like it was written by a C++ programmer who stumbled 
-	across a Python manual!</li>

 </ul>
 <h2>11.2 Strategies</h2>
 <p>To meet these goals, the following strategies were used:</p>
 <ul>
 	<li>A powerful configuration parser,
 	<a href="http://www.voidspace.org.uk/python/configobj.html">ConfigObj</a>, by 
-Michael Foord and Nicola Larosa, was chosen to read the configuration file. This 
-allows many options that might otherwise have to go in the code to go instead in 
-a configuration file.</li>
+	Michael Foord and Nicola Larosa, was chosen to read the configuration file. 
+	This allows many options that might otherwise have to go in the code to go instead 
+	in a configuration file.</li>
 	<li>A powerful templating engine, <a href="http://www.cheetahtemplate.org/">
-	Cheetah</a>, was used. This allows many variables that I may not have 
-	thought of to be accessed from within the HTML templates, without starting 
-	to modify the code.</li>
-	<li>A largely stateless design style. For example, many of the processing 
-	routines read their own data from the database, rather than caching it and 
-	sharing with other processing routines. While this means the same data may 
-	be read multiple times, it also means the only point of possible cache 
-	incoherence is through the database, where transactions are easily 
-	controlled. This greatly reduces the chances of corrupting the data, making 
-	it much easier to understand and modify the code base.</li>
-	<li>No static variables (except read only variables) to make it easy to 
-simultaneously support multiple weather stations and to allow some level of 
-multithreading.</li>
-	<li>Pure Python. The code base is 100% Python &mdash; no underlying C 
-	libraries need be built to install <span class="code">weewx</span>. </li>

 </ul>
-<p>While <span class="code">weewx </span>is nowhere near as fast at generating images and HTML as its 
-predecessor, <span class="code">wview </span>(this is partially because it uses fancier fonts and a way more 
-powerful templating engine), it is &#39;fast enough&#39; for all platforms but the 
-slowest. I run it regularly on a 500 MHz machine where generating the 9 images 
-used in the &quot;Current Conditions&quot; page takes just under 2 seconds. Compare this 
-with <span class="code">wview</span>&#39;s 0.4 seconds.</p>

 <h2>11.3 Run time internals</h2>
 <p>Three threads are used within <span class="code">weewx</span>:</p>
 <ol>
-	<li>The main thread of the program is used to monitor the
-	VantagePro and, by definition, is active the entire lifetime
-	of the program. All interactions with the hardware go through
-	it. On program startup, the main thread starts by downloading
-	any data from the VP that has been stored on board, but not
-	yet put in the
-	<span class="code">weewx</span> archive database. If the
-	statistical database doesn&#39;t exist (nominally located at
-	<span class="code"><em>$WEEWX_ROOT</em>/archive/stats.sdb</span>),
-	or is out of date, then it will repopulate the missing data
-	from the main database. Finally, it sets up a thread (thread
-	#2 below) to publish data to the Weather Underground (WU) and
-	other sites that interact through HTTP.
-
-	  <p>Once finished with these startup chores, the main thread
-	  then puts the VantagePro in LOOP mode. In this mode, the VP
-	  offers up data every 2 seconds, sleeping in between. This is
-	  a very energy saving mode. The thread monitors the port and
-	  when new data is available, it adds it to the running
-	  statistical tally, in particular highs, lows, and wind rms
-	  data, kept in the stats database. While in LOOP mode, very
-	  little processing is done so it doesn&#39;t miss any
-	  updates.</p>
-	  <p>When an archive interval is due, typically every 5
-	  minutes or so, then the main thread cancels the LOOP mode,
-	  and then downloads the new archive data, putting it in the
-	  main database. It also uses the archive data to update
-	  averages in the stats database. It puts the new record in a
-	  Queue to be sent to the Weather Underground. It then creates
-	  and starts thread #3 to do any processing of the data.</p>
-</li>
-<li><p>Thread #2 interacts with the Weather Underground. It is also active the 
-entire lifetime of the program. It monitors a Queue. When new data appears in 
-the Queue, this thread forms the necessary URL to send it
-to the WU and then sends it. It then goes back to monitoring the
-queue. This way, posting data on the WU can happen asynchronously with
-other processing.</p></li>
-<li><p>Thread #3 is responsible for generating HTML files, images, and
-NOAA monthly and yearly reports. Its lifetime is only as long as it
-takes to process a new archive record and then it dies. Because most
-of the tricky processing happens in this thread, this is the most
-likely place where an exception could occur. However, should this
-happen, it will only affect this short-lived thread, and not the much
-longer-lived main thread. Hopefully, this means that at least no data
