This package implements formal Laurent series expansions in one variable
using the domain mechanism of REDUCE. This means that power series
objects can be added, multiplied, differentiated etc., like other first
class objects in the system. A lazy evaluation scheme is used and thus
terms of the series are not evaluated until they are required for printing
or for use in calculating terms in other power series. The series are
extendible giving the user the impression that the full infinite series is
being manipulated. The errors that can sometimes occur using series that
are truncated at some fixed depth (for example when a term in the required
series depends on terms of an intermediate series beyond the truncation
depth) are thus avoided.
