It seems to me that this is the important part. The simplest processing
of a command line might not count as parsing.

If one processes an arithmetic expression left to right, with no precedence,
that might not count as parsing. Is two different precedence levels enough?

My first thought of the question was for machine generated vs.
hand written parsers.  When does it get complicated enough to make
it worth using a parser generator?
