Ack, but sometimes you get data from files which are not disk files,
and you could get it at runtime, and not at start time.

I have not a parser, but a string splitter in:

http://turkos.aspodata.se/git/c/libaspoutil/parse.c
http://turkos.aspodata.se/git/c/libaspoutil/parse.h

It splits a string in what I belive shell style. What you do with the
tokens that is your business. It could use some love on the doc side
and some real world testing.
