Due some conflation between Fresnel the project and Fresnel the
codebase, the examples/ directory is a bit ambiguous; its intended
purpose is to be examples of the Fresnel vocabulary, not necessarily
compatible with the codebase I wrote. Because Fresnel is based on
Sesame, the parser limitations (Turtle instead of full N3) are a barrier
in using all of the examples. I could rewrite the examples as Turtle,
but information gets lost that way. I'd rather rewrite the parser to do
full N3 instead.

This one was modified and should work, though:

Note also that using my FOAF file is decidedly less interesting now
since I removed all the foaf:knows statements at some point after I
wrote those example usage messages.

Your contributions would be more than welcome.

I believe that's the Sesame parser (Rio)'s way of saying line, column.
