Partly updated to reflect the new organization and the availability of CVS 

access. Will still need a bit of work when all plugins are separated, probably.

This document explains how to build MacPython from source. This is
necessary if you want to write extension modules for 68K Python, and
currently also probably the easiest way to build PPC extension
modules. Building Python is not something to be undertaken lightly,
the process is not very streamlined so you need a reasonable working

<H2>Using the CVS source archive</H2>
It is possible to access the Python sources through remote CVS if you are
a PSA member. The advantage of this is that you get the very latest sources,
so any bug fixed or new features will be immedeately available. This is also
the disadvantage, of course: as this is the same tree as is used for development it
may sometimes be a little less stable. <p>
The CVS client of choice is Alexandre Parenteau's MacCVS. It can be
obtained through the <a href="http://www.cyclic.com">Cyclic CVS homepage</a>. MacCVS
uses Internet Config to set file types correctly based on the filename extension. In
the maccvs preferences you should also set (in the "binary files" section)
"use mac encoding: applesingle" and (in the "text files" section) "use ISO latin 1
conversion". <p>
The machine-independent Python sources are checked out from the main Python
CVS archive, see the <a href="http://www.python.org/psa">PSA homepage</a> for
details. <p>
Next, within the toplevel Python folder, you check out the mac-specific sources
in a Mac folder. The CVS path to use can be found at the
<a href="http://www.cwi.nl/~jack/macpython.html">MacPython homepage</a>. Finally,
you check out the external libraries needed in the parent of the Python folder. The
CVS path for these libraries is also mentioned at the MacPython homepage. <p>
