I think you want is:

= A Heading =

== A less important heading ==

BTW, I'm pretty excited about that wiki page. I recently got my first
Mac (17" Intel iMac) and have had a lot of difficulties with the apps on
that wiki page (I a few data analysis scripts using SciPy). It seemed
like anything using Fortran was doomed to failure. I finally got Numpy
and Scipy (from SVN) installed using gfortran (gfortran-intel-bin.tar.gz
from http://hpc.sourceforge.net/) and the  Universal MacPython 2.4.3c1
build from Ronald Oussoren. I followed the directions at
http://www.scipy.org/Installing_SciPy/Mac_OS_X . I can update the wiki
page when I get a chance.

[Pythonmac-SIG] Python Universal packages- how can I help

[Jordan Mantha]

Hi all!
Ok, so I recently got my first mac, an Intel iMac (17") for work.  
So far I have been totally impressed. I really enjoy OSX and starting  
to get into Python more.  However, I'm starting to feel bad that I  
have this thing and I'm not helping with testing/building Universal  
packages for other people to enjoy. I'm particularly interested in  
scientific python packages (scipy and friends, matplotlib, pyx, etc.)  
and wxpython. Is there a general place to find tutorials or something  
on creating Universal python packages? I'd like to help fill in  
http://pythonmac.org/wiki/UniversalPackages if I can. How would I go  
about doing that?

Thanks,
Jordan Mantha

Thanks for the info. I'll try to check those points. The universal
builds sound a bit scary, which is probably the reason they aren't all
over the place. I would assume creating Intel-only packages is easier,
is that right? Can bdist_mpkg (and py2app for that matter) be used on
Intel macs with the Universal Python 2.4.3 build? I'd like to learn how
to use bdist_mpkg and py2app. I'm having a bit of trouble figuring where
various packages are when it comes to Intel compatibility. Would making
.mpkgs be a more realistic goal? Sorry if my questions are seeming
silly. I'm used to building from source for myself and Linux packaging.

I just got the psyco svn checkout and ran "sudo python setup.py  
install". I wasn't sure what to use as a test so I just used pystones.

No Psyco
python -c "from test.pystone import pystones; print pystones()"
(1.1899, 42016.806722689078)
python -c "from test.pystone import pystones; print pystones(10)"
(2.4101, 41493.775933609955)

With Psyco
python -c "from test.pystone import pystones; import psyco; psyco.full 
(); print pystones()"
(0.22, 227272.72727272726)
python -c "from test.pystone import pystones; import psyco; psyco.full 
(); print pystones(10)"
(0.42999, 232558.13953488372)

I repeated each test a couple times. Looks like psyco works.
