ini files and plugins

[tool69]

Hi,
I've made a basic LaTeX file editor in wxPython, but now I wanted to add 
it some features :

1 -  create a sort of ini file where I can put the user configuration 
that will load itself on the application startup ;
2 -  a simple plugin system with python files ( maybe to add new 
langages, etc.) ;

I'm looking for simple articles, modules or code snippets on these 
subjects;
thanks,
