A REDUCE Limits Package

LIMITS is a fast limit package for REDUCE for functions which are
continuous except for computable poles and singularities, based on some
earlier work by Ian Cohen and John P. Fitch. The Truncated Power Series
package is used for non-critical points, at which the value of the
function is the constant term in the expansion around that point.
l'Hôpital's rule is used in critical cases, with preprocessing of
forms and reformatting of product forms in order
to apply l'Hôpital's rule. A limited amount of bounded arithmetic
is also employed where applicable.
