There are 66 files, each fairly complex.  This is not a trivial 
undertaking, but the algorithms for each are published in the ACM. If we 
can't use the code, we can still use the algorithms.  The real issue is 
that we should probably get a little more serious than that if we really 
have to go that way.  Those older routines were very heavily optimized 
for the computers of 1984, and many of those constraints have changed 
(to say the least).
