I see. I'd assumed it was production-quality :-(

OK. good to know. I'd assumed there'd be a font directory 
under python path somewhere.

(I had a wierd error from freefont a while ago, which took 
ages to track down. It was due to a bunch of fonts in 
/usr/lib/fonts, which is where ghostscript used to look for 
them. I had to remove that directory for the error to go 
away. There's nothing in the freefont/freetype documentation 
about looking outside its own font directories or in google 
to handle the error. Why can't everyone agree on a single 
directory for fonts for heaven's sake, or if they're going 
to use a different directory, to ignore the places everyone 
else puts their fonts. mutter, mutter)

got it.

will get on to it.

Thanks. If the code looks normal to a python person that's 
near enough to canonical for me.
