Document how to run against local lists

[mgifford]

From this:

1. A text file with a list of links
2. A XML file with XML tags in Sitemap Protocol format

It sounds like I should be able to run this against a local file on my local system, but I can't seem to get the formatting to accept a local path.

Closest I can come gives me this error:
