    (description
     "Leiden is a general algorithm for methods of community detection in
large networks.  This package implements the Leiden algorithm in C++ and
exposes it to Python.  Besides the relative flexibility of the implementation,
it also scales well, and can be run on graphs of millions of nodes (as long as
they can fit in memory).  The core function is @code{find_partition} which
finds the optimal partition using the Leiden algorithm, which is an extension
of the Louvain algorithm, for a number of different methods.")

descriptions and produces PNG, SVG, EPS or server side image maps (ismaps) as
the output.  Message Sequence Charts (MSCs) are a way of representing entities
and interactions over some time period and are often used in combination with
SDL.  MSCs are popular in Telecoms to specify how protocols operate although
MSCs need not be complicated to create or use.  Mscgen aims to provide a simple
text language that is clear to create, edit and understand, which can also be
transformed into common image formats for display or printing.")
