many bug fixes and improvements such as:
* small improvement to Arg(...) working on real numbers.
* improved 'make test', no need to install before test any more.
* VarList can now accept a second argument, a filter predicate.
* Pattern     matcher     now    allows    extended    prototypes,    like
  PP(list_Contains("a")) <-- ... etcetera.
* c-style  tokenizer  using CTokenizer() (DefaultTokenizer() switches back
  to the default tokenizer).
* Great speed-up of function Assoc.
* Christian   Obrecht   implemented  the  Rabin-Miller  primality  testing
  algorithm, which greatly improves the speed of IsPrime.
* Orthogonal      polynomials     OrthoP,     OrthoP,OrthoG,OrthoH,OrthoL,
  OrthoT,OrthoU implemented by Serge Winitzki.
* various  speedups,  and  a  new memory manager, optimized for allocating
  many small blocks (which is the case in Yacas).
* Changed the directory structure for the script files
* Greatly improved Simplify function.
* Added CurrentFile, CurrentLine functions
* Implemented  backquote  mechanism:  `(...) will substitute every @@a with
  the  evaluation  of  a  (and  if  a  is  a function the function name is
  replaced).  The  end  result  is  evaluated. see substitute.cpp for more
  details

many more...  see http://www.xs4all.nl/~apinkus/changes.html for the complete
list.

@Initial import of yacas-1.0.28

Yacas (Yet Another Computer Algebra System) is a small and highly flexible
computer algebra language. The syntax uses a infix-operator grammar
parser. The distribution contains a small library of mathematical functions,
but its real strength is in the language in which you can easily write your
own symbolic manipulation algorithms. It supports arbitrary precision
arithmetic.

The current version is 1.0.28 (the first release was 1.0.0). The language is
very much in a finished state. Any code written for it should be usable in
future versions. Also, the language should prove very easy to learn.

Yacas is written in very clean c++ code, and is very portable . It can compile
stand-alone, and is easily embeddable. Yacas contains a native arbitrary
precision arithmetic module, but can also be used with GMP.

Things implemented include: arbitrary precision, rational numeric, vector,
complex, and matrix computations (including inverses and determinants and
solving matrix equations), derivatives, solving, Taylor series, numerical
solving (Newtons method), and a lot more non-mathematical algorithms. The
language natively supports variables and user-defined functions. There is
basic support for polynomials.
