heh. demo code is probably never production quality. it is for demo. 
production quality requires details of your production environment. demo 
code almost always assumes you run from the demo path and have all you 
need in the demo path.

david is right about the current path. relative paths will be relative 
to your current path. you can get and set that with os.getcwd and 
os.chdir. the current path is usually where you started python.

the python path is for code. python uses your os for font management.

that's what chkfontpath and fontconfig are for.

Canonical is as David said and then create a setup.py and use either the 
sdist option to create a source distribution or the bdist_egg option to 
create an egg. Both are zipped and ready for distribution/deployment.
