Download and Installation
=========================

The current version of |PACKAGE_NAME| is |release|.

Registration
------------

The download is password protected. To get the password, send an email
to `Peter Paule <http://www.risc.jku.at/home/ppaule>`_ . It will be
given for free to all researchers and non-commercial users.

Note that redistribution of RISCErgoSum is not allowed.

Short Instruction
-----------------

Get one of the files |PACKAGE_TARNAME|-|release|.tgz or
|PACKAGE_TARNAME|-|release|.zip from
http://www.risc.jku.at/research/combinat/software/source/mathematica/ergosum
and extract it in the ``Applications`` subdirectory of your local
Mathematica ``$UserBaseDirectory``.

Detailed Instruction
--------------------

Start Mathematica and type::

  $UserBaseDirectory

at the command prompt.

Suppose this value is ``/home/hemmecke/.Mathematica``. Exit
Mathematica and extract the .tgz file into the ``Applications``
subdirectory.

Under Linux (substitute appropriately)::

  tar xvzf riscergosum-x.y.z.tgz -C /home/hemmecke/.Mathematica/Applications

Under MacOS the output from ``$UserBaseDirectory`` will most probably
look similar to ``/Users/hemmecke/Library/Mathematica``.
Thus, in a terminal type::

   tar xvzf riscergosum-x.y.z.tgz -C /Users/hemmecke/Library/Mathematica/Applications
Note that the ``Library`` folder is usually hidden in the file browser.

Under Windows (substitute appropriately) unzip the
``riscergosum-x.y.z.zip`` and move the files (and subdirectories) to
``$UserBaseDirectory/Applications``.

After extracting the files into the ``Applications`` subdirectory, you
should find there the subdirectories ::

  Applications/RISC
  Applications/InvEulerPhi

and in particular the file ::

  Applications/RISC/MultiSum.m

If you don't see ``RISC`` and ``InvEulerPhi`` directly under
``Applications``, then something went wrong and the following will not
work.

Start Mathematica and type::

  << RISC`MultiSum`

You should then see something like::
