- \subsection{The CVS Tree}
- 
- In May 2000, the Python CVS tree was moved to SourceForge
- (\url{http://www.sf.net}), and the bug tracking and patch submission tools
- offered by SourceForge were also adopted at that time.  Using
- SourceForge's admittedly erratic project activity ranking, Python is
- often among the 10 most active projects.
- 
- Anyone can check out a read-only copy of the CVS tree by using
- anonymous CVS.  First, you'll need to run the following command to anonymously log in to the CVS server:
- 
- \begin{verbatim}
- cvs -d:pserver:ano...@cv...:/cvsroot/python login
- \end{verbatim}
- 
- Then, you can check out the tree:
- 
- \begin{verbatim}
- cvs -z3 \ 
-   -d:pserver:ano...@cv...:/cvsroot/python \
-   co python
- \end{verbatim}
- 
- Running \code{cvs -z3 update} will update the CVS tree to the most
- recent version.  Checkin messages and the accompanying diffs are sent
- to a mailing list, \email{python-checkins}.  Anyone can subscribe by
- going to \url{http://mail.python.org/mailman/listinfo/python-checkins}.
- 
- Write access to the Python CVS tree is not automatically granted,
- though there's no formal process to go through to get it.  If the
- python-dev team knows who you are, whether through mailing list
- discussion, having submitted patches, or some other interaction, then
- you can ask for full CVS access.  You'll need to have a SourceForge
- ID, and provide it with your request.

  \subsection{Bug Tracking}

! To report a bug in Python, use the bug tracking tool at \url{http://sourceforge.net/tracker/?group_id=5470\&atid=105470}.
  Don't report bugs by posting them to a mailing list, or sending them
  to a particular developer as a private e-mail; most likely the bug

+ \subsection{Design Principles}
+ 
+ Each software project in the world has its own culture and style, its
+ own approach to designing solutions to problems.  Python has its own
+ style, of course, and if you've learnt the language then that style
+ has probably rubbed off on you to some extent.  Python tries to keep
+ things simple, to be orthogonal but not too much so, to assist the
+ user as much as possible.  
+ 
+ In June 1999, Tim Peters channeled Guido and listed 19 guiding
+ principles for Python's design in a \newsgroup{comp.lang.python}
+ posting.  The principles shouldn't be taken too seriously, as they're
+ not hard-and-fast constraints and for each rule you can probably list
+ instances where it's been broken.  Still, no one has had much
+ disagreement with this list of design criteria.
+ 
+ \begin{enumerate}
+ \item    Beautiful is better than ugly.
+ 
+ \item    Explicit is better than implicit.
+ 
+ \item    Simple is better than complex.
+ 
+ \item    Complex is better than complicated.
+ 
+ \item    Flat is better than nested.
+ 
+ \item    Sparse is better than dense.
+ 
+ \item    Readability counts.
+ 
+ \item    Special cases aren't special enough to break the rules.
+ 
+ \item    Although practicality beats purity.
+ 
+ \item    Errors should never pass silently.
+ 
+ \item   Unless explicitly silenced.
+ 
+ \item   In the face of ambiguity, refuse the temptation to guess.
+ 
+ \item There should be one --- and preferably only one --- obvious way
+       to do it.
+ 
+ \item    Although that way may not be obvious at first unless you're Dutch.
+ 
+ \item    Now is better than never.
+ 
+ \item    Although never is often better than \emph{right} now.
+ 
+ \item    If the implementation is hard to explain, it's a bad idea.
+ 
+ \item   If the implementation is easy to explain, it may be a good idea.
+ 
+ \item   Namespaces are one honking great idea --- let's do more of those!
+ 
+ \end{enumerate}
+ 
+ Don't take these 19 aphorisms too seriously --- tattooing them on your
+ body is probably a bad idea, for example --- but it's instructive to
+ contemplate them.  Some parallels can be drawn to the guiding
+ principles of extreme programming, most notably the emphasis on ``Do
+ the simplest thing that can possibly work''.
