doc: document lib, fix formating/example Add lib as an optional directory in a template. Make config_ini.ini example an actual code block using the file from the jinja2 template. Format the TEMPLATE-INFO.txt example as plain text (it was highlighting words like 'in' and 'with'). Also move the whole example under the bullet item, it was outside of the list. Reformat the input text to be less than 80 characters.
