The "application" is very simple - its essentially a finite state
machine that parses complex RTF files. We read char by char and do lots
of string concatenation as we move through our various states. Using
lists for concatenation and Emile's technique of eliminating repeated
attribute lookups, we have significantly improved the performance of our
utilities.
