\BEG

In this example, indefinite integral of the rational function

@code{x^6/(x^5+x+1)} is computed.

The result is a list which comprises two elements:

The first element is the rational part of the integral;

The second part is the logarithmic part of the integral.

The logarithmic part is again a list which comprises finite number of

elements, each of which is of form @code{[root*log(poly),defpoly]}.

This pair should be interpreted to sum up

the expression @code{root*log(poly)}

through all @b{root}'s @code{root}'s of the @code{defpoly}.

Here, @code{poly} contains @code{root}, and substitution for @code{root}

is equally applied to @code{poly}.

The logarithmic part in total is obtained by applying such

interpretation to all element pairs in the second element of the

result and then summing them up all.

\BEG

Primary ideal decomposition of polynomial ideals and prime compotision

of radicals

(Refer to @code{[Shimoyama,Yokoyama]}).

@code{primadec()}, @code{primedec()} are the function for primary

ideal decomposition and prime decomposition of the radical respectively.

The arguments are a list of polynomials and a list of variables.

These functions accept ideals with rational function coefficients

and non zero-dimenstional ideals.

@code{primadec} returns the list of pair lists consisting a primary component

and its associated prime.

@code{primedec} returns the list of prime components.

Each component is a Groebner basis and the corresponding term order

is indicated by the global variables @code{PRIMAORD}, @code{PRIMEORD}

respectively.

@example

Four years have passed since the last distribution.

Though the look and feel seem unchanged, internally there are

several changes such as 32-bit representation of bignums.

Plotting facilities are not available on Windows.

If you have files created by @code{bsave} on the older version,

you have to use @code{bload27} to read such files.
