New items in core:
* general mechanism for functions to distribute over operators
(distribute_over declaration)
Other revisions:
* improved Laplace transforms of special functions
* assume database:
The inferences between the declarations of variables as integer,
real, complex, .. have been cut out. The constant %i is declared
to be imaginary. The constants %pi, %e, %gamma, %phi are declared
to be real.
The database handles expressions with constants more completely.
Facts like assume(x < %pi/2) are now handled correctly.
The sign of sums of constant expressions is determined more
correctly.
Askinteger take into account more facts from the database.
* improvements of special functions:
More functionality for the Hankel 1 and 2 functions:
Expansion for a half integral order has been implemented.
More consistent numerical evaluation of Bessel and Hankel functions.
More general integrals for Bessel functions and implementation of
integrals for the Airy functions.
Gamma function accepts a Taylor expansion as an argument.
Implementation of Struve H and L functions:
Numerical evaluation for real and complex numbers in float and
bigfloat precision. Handling of specific values. Derivatives of the
functions and expansion for a half integral order is implemented.
Adding mirror symmetry for the Airy functions.
Improving the limits of the log and factorial functions.
* package fft: revised for greater speed
* package to_poly_solver: improvements
* regularize error and warning messages, and translate via gettext (ongoing)

variables are all lowercase only
* Regularize case in printed messages

* Additional tutorial documents
* Discrete plots (for plot2d)
* Enhancements to tensor packages (Atensor, Ctensor, Itensor)
* Replaced Airy functions with much more extensive implementation
* Revisions to Bessel functions
o Bessel functions with real order and complex argument can be
evaluated numerically.
o bessel_j can be computed for negative real order.
* Revisions to gamma function
o Gamma function can be numerically evaluated for complex arguments.
* Revisions to elliptic functions
o Bugs 1165488 and 908185 fixed.
o Fixed issue where many of the routines were returning single-float
results instead of double-float when given rational args.
o elliptic_f with complex args can be numerically evaluated.
o Other inverse Jacobi routines can be evaluated at complex points.
* Extensive revisions to hypergeometric functions
o Adjusted routines to return the new names for the Bessel functions
(like bessel_j instead of %j).

conventions used by the specfun orthogonal polynomial package.
o Corrected many errors in implementation.
o Some missing internal functionality added.

developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.
