The Info file format is an easily-parsable representation for online documents. It can be read by emacs(1) and info(1) among other programs.
Info files are usually created from texinfo(5) sources by makeinfo(1) , but can be created from scratch if so desired.
For a full description of the Texinfo language and associated tools, please see the Texinfo manual (written in Texinfo itself). Most likely, running this command from your shell: info texinfo or this key sequence from inside Emacs: M-x info RET m texinfo RET will get you there.
or any GNU mirror site.
