This message announces the availability of JACAL release jacal1b0.

New in jacal1b0:

	* hensel.scm (poly:factorz): Issues messages for multivariate
	factoring when math:trace is on.
	* hensel.scm (poly:factorszpp): Fixed factoring for multivariate
	polynomials whose leading coefficients have repeated factors.
	* hensel.scm (map-svpf-factors): abstracted from poly:factorz.
	* ff.scm (number->poly): moved from hensel.scm.
	* ff.scm (u:factorz): Integrated into poly:factorz.
	* hensel.scm (poly:factorszpp): put limits on number of random
	ideals and primes tried.
	* vect.scm (mtrx:inverse): Added.
	* toploads.scm (*catalog*): "usercat" didn't work from other
	directories;  Augment *catalog* directly.
	* sexp.scm (defbltn): Extra definition removed.
	(sapply): Constant functions now represented by the constant.
	* builtin.scm (factors):
	(factor): now accept equations as argument.
	* sexp.scm (*->or-eqns): Added to factor equations.
	* jacal.texi (Algebraic Commands): documented extrule.

JACAL is a symbolic mathematics system for the simplification and
manipulation of equations and single and multiple valued algebraic
expressions constructed of numbers, variables, radicals, and algebraic
functions, differential, and holonomic functions.  In addition,
vectors and matrices of the above objects are included.

JACAL is written in Scheme.  A version of Scheme (IEEE P1178 and R4RS
compliant) written in C is available with JACAL.  SCM runs on Amiga,
Atari-ST, MacOS, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Unix and similar
systems.

Documentation is included in the distribution.  Documentation is also
online at:

	    http://swissnet.ai.mit.edu/~jaffer/JACAL.html

JACAL source is available via FTP (detailed instructions follow) from:
 swissnet.ai.mit.edu:pub/scm/jacal1b0.zip
 ftp.gnu.org:pub/gnu/jacal/jacal1b0.zip

SLIB is a portable scheme library which JACAL requires:
 swissnet.ai.mit.edu:pub/scm/slib2c6.zip
 ftp.gnu.org:pub/gnu/jacal/slib2c6.zip

SCM is a small Scheme implementation under which JACAL will run.
 swissnet.ai.mit.edu:pub/scm/scm5d1.zip
 ftp.gnu.org:pub/gnu/jacal/scm5d1.zip

Programs for printing and viewing TexInfo documentation (which JACAL
has) come with GNU Emacs or can be obtained via ftp from:
 ftp.gnu.org:pub/gnu/texinfo-3.1.tar.gz
