Virtual Laboratory Environment: Python binding
==============================================

See AUTHORS and COPYRIGHT for the list of contributors.

VLE is an operational framework for multi-modeling, simulation and analysis of
complex dynamical systems. It addresses the reliability issue by using recent
developments in the theory of modeling and simulation proposed by B. Zeigler
with the Discrete Event System Specification formalism (DEVS).

Installation
------------

The following commands configure, build and install VLE into your account:

$ tar zxf pyvle-0.9.0.tar.gz
or
$ git clone git://vle.git.sourceforge.net/gitroot/vle/pyvle

1. Installation in the distribution directory

    If you wan to install pyvle into the classical python directory
    (/usr/lib/python-2.x/), just follow the commands:

    $ cd pyvle
    $ mkdir build
    $ cd build
    $ cmake -DCMAKE_INSTALL_PREFIX=/usr
            -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
    $ make
    $ make install

2. Installation in $HOME directory:

    If you want to install pyvle into your $HOME (or any other directory)
    directory, you need to add an environment variable PYTHONPATH into your
    shell. For instance for bash, add the following line. Update the python2.6
    with the version of the python you use:

    PYTHONPATH=$HOME/usr/lib/python2.6:$HOME/usr/lib/python2.6/lib-dynload

    $ cd pyvle
    $ mkdir build
    $ cd build
    $ cmake -DCMAKE_INSTALL_PREFIX=$HOME/usr
            -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
    $ make
    $ make install
