Agreed.  I don't necessarily think that we need to rip out the
functions nor simply remove the reference to Numerical Recipes.  If it
turns out that we all ready have (or could easily have with a quick
rewrite) code that is based on the algorithms described in Numerical
Recipes (but not *derived* from their code), we should leave them in
and make sure to clarify in the comments that this is the case.
