format of infofiles

[TS Pereira]

Hi,

This is my first post to this list, so sorry if it is inappropriate.

I'm currently coding a Gtk based tree-heirarchy infofile reader 
(http://www.cs.bris.ac.uk/~nathan/programming/ginfotree/) and was wondering if 
anyone could point me in the direction of some official infofile format 
documentation, or at least a list of conventions that info/emacs follows when 
reading files that my reader should mirror.

Thanks for your time,
Tom.
