 SNAKES is the Net Algebra Kit for Editors and Simulators

-SNAKES is a Python library that provides all then necessary to define
-and execute many sorts of Petri nets, in particular those of the PBC
-and M-nets family. Its main aim is to be a general Petri net library,
-being able to cope with most Petri nets models, and providing the
-researcher with a tool to quickly prototype its new ideas. SNAKES
-should be suitable to provide the data model for editors or
-simulators; actually, any editor that use SNAKES may also be a
-simulator as SNAKES can execute any net.
+SNAKES is a Python library that provides all the necessary to define
+and execute many sorts of Petri nets, in particular algebras of Petri
+nets. SNAKES' main aim is to be a general Petri net library, being
+able to cope with most Petri nets models, and providing the researcher
+with a tool to quickly prototype new ideas.
 
 A key feature of SNAKES is the ability to use arbitrary Python objects
 as tokens and arbitrary Python expressions in many points, for
 instance in transitions guards or arcs outgoing of transitions. This
-is what makes SNAKES that general. This relies on the capability of
-Python to run dynamically provided Python code (the $eval$ function).
-This feature may not be efficient enough for model-checking: speed is
-the price to pay for the wide generality. However, in the case of a
-new model, SNAKES may happen to be the only available tool.
+provides out of the box a great flexibility.
 
 Another important feature of SNAKES is the plugin system that allows
-to extend the features and work with specialised classes of Petri
-nets. Currently, the following plugins are provided:
-
-pos:: adds to nodes the capability of holding their position. Nodes
-can be moved or shifted, Petri nets can be shifted globally and their
-bounding box can be computed.
-
-gv:: adds a method to draw a Petri net or a state graph using the tool
-http://www.graphviz.org[GraphViz] (through the Python binding
-http://networkx.lanl.gov/wiki/pygraphviz[PyGraphViz]). This module
-replaces the previous plugin called _graphviz_ and provides more
-flexibility and security, _graphviz_ is still provided but deprecated.
-
-status:: extends the Petri net model by adding status to the nodes.
-This is similar to what is used in the models of the PBC or Mnets
-family. Nodes can then merged automatically according to their status.
-
-ops:: this plugins defines control flow operations on Petri nets
-usually found in the PBC and Mnets family. Nets can be composed in
-parallel, sequence, choice and iteration. These operations rely on the
-places status.
-
-labels:: allows to add arbitrary labels to most objects (places,
-transitions, nets, ...)
-
-posops:: combines the features of pos and ops plugins: the control
-flow operations are modified in order to rearrange the nodes position
-in order to provide well shaped nets. This plugin is deprecated
-because the new _gv_ does the work much better.
-
-synchro:: it defines the label-based transition synchronisation
-defined in the Mnets model.
-
-// export:: allows to save Petri nets objects in the format of the tools
-// http://pep.sourceforge.net[PEP], http://helena.cnam.fr[Helena] and
-// http://maria[Maria]. http://pnml[PNML] is also supported as it is
-// built-in SNAKES.
-
-lashdata:: allows to define data that is not handled in the places of
-the Petri net but stored instead in the special structures handled by
-the http://www.montefiore.ulg.ac.be/~boigelot/research/lash/[library
-Lash]. This allows in particular to aggregate possibly infinite states
-into one meta-state.
-
-clusters:: this is an auxiliary plugin that allows to group nodes in a
-Petri net. This feature is used by _ops_ in order to record how a net
-is constructed, which is exploited by _gv_ in order to build a nice
-layout of composed nets.
-
+to extend the features, for instance to work with specialised classes
+of Petri nets (e.g., plugins are provided to draw nets, or to compose
+them using the various control-flows operations). Plugins are another
+way to introduce flexibility but requiring some involvement.
 
-Getting SNAKES and installing it
---------------------------------
+Next step to use SNAKES should be to read the tutorial that describes installation and first steps.
 
-Download http://www.univ-paris12.fr/lacl/pommereau/soft/snakes/snakes-{VERSION}.tar.gz[$snakes-{VERSION}.tar.gz$]
-({sys:../stat snakes-{VERSION}.tar.gz})
+Useful links
+------------
 
-To install SNAKES, uncompress the archive and copy the directory
-snakes in a location where Python can find it (_i.e._, in a directory
-listed in your $PYTHONPATH$ environment variable).
+- SNAKES homepage (documentation, tutorial, API reference, ...)
+  http://www.ibisc.univ-evry.fr/~fpommereau/SNAKES/
+- SNAKES development page (source repository, history, bug reports,
+  feature requests, ...)
+  http://code.google.com/p/python-snakes
+- Ubuntu packages
+  http://launchpad.net/~pommereau/+archive/ppa    
 
-SNAKES should work with a Python version at least 2.5 but will _not_
-work for an older version. Optionally, you may want to install
-additional software required by some plugins:
+Copyright
+---------
 
-gv:: depends on http://www.graphviz.org[GraphViz] and its Python
-   binding http://networkx.lanl.gov/wiki/pygraphviz[PyGraphViz]. The
-   plugin _graphviz_ depends on GraphViz only but is now deprecated.
-
-lashdata:: requires
-   http://www.montefiore.ulg.ac.be/~boigelot/research/lash[Lash] and
-   the
-   http://www.univ-paris12.fr/lacl/pommereau/soft/index.html#PyLash[Python
-   Lash binding].
