Let's say I don't have an RSS feed of sources, but a local file that provides sections, titles and URLs of articles.
I would like a recipe, probably something with def parse_index, that would read the file instead of the RSS, then fetch the articles from the internet and make nice ebook with sections and cover image (also a file on local system!). The syntax of file is not defined yet, the python master can assume whatever format is most useful.

E.g.:
[The title of section1]
Title
smalltext
url
title
smalltex
url
[Section2]
title
smalltext
url
.
.
I was thinking about making my own custom RSS, but I guess this could be probably done directly in recipe in a much more elegant way.
I'm sure such universal recipe would be useful.
So, basically I'm asking for a parse_index that would parse a local file.
