Feel free to change it, it’s a wiki.

In my own document the functions live in an environment, together with  
all the definitions for the letter, and the invoice items in the  
actual invoice document. I wanted to make a rather minimal example, so  
I left out all the letter stuff.

The page is of use only for those who speak little Lua (I was looking  
for a similar example); if you know better, you won’t need it, and if  
you don’t speak Lua at all, it’s useless for you.
