With a class it *does* work:
In [74]: class Pardon(type):
a function as metaclass. But that seems to
be part of the specification. The function result is what the 'class' becomes.
You can even have it return something else. Then the 'class' wouldn't really be

'From first' is the result of the class definition. 'from second' is the result

I have a 64 bit server with CentOS 4.3 installed, running Python.
[EMAIL PROTECTED] pymsnt-0.11.2]$ uname -a
Linux lutetium.mxit.co.za 2.6.9-34.ELsmp #1 SMP Thu Mar 9 06:23:23 GMT
2006 x86_64 x86_64 x86_64 GNU/Linux
Consider
the program under test runs so I have
little idea what to expect.
To mangle graphs and their drawing via graphviz on multilple platforms,
you might also want to try networkx combined with pygraphviz
(available from networkx.lanl.gov)
Cheers, Pieter

what about the following?
f = open( 'file.txt', 'r' )
lines = f.readlines()
f.close()
f = open( 'file.txt'.'w' )
f.write( '\n'.join( lines[1:] ) )
f.close()
cheers,
pieter

The following should work:
os.path.split( os.path.realpath( sys.argv[0] ) )[0]
