A reference is the tutorial I gave at the compiler construction
conference some years ago. The point is that efficient lexical
analyzers are very easy to write, it is pretty much as easy to
write such as to generate the tables for an automatic tool, and
most of the automatic tools are horribly slow (they are one of
many tools in our relatively recently developed technology of
horribly slow compilers :-)
