r"""
read a .ftbl file from a parameter (or from --prefix/--mtf options) and translate to .xgmml file.
The generated xgmml file can be then imported into Cytoscape
(www.cytoscape.org).
Reactions involving two substrates or two products are represented
by an additional almost invisible node while one-to-one reactions
are just edges.
Node and edge attributes are written in respective xml attributes.
Compatibility: cytoscape v2.8.3 and v3.0

usage: ftbl2xgmml.py [-h|--help] mynetwork.ftbl|--prefix PREFIX|--mtf MTF [> mynetwork.xgmml]

OPTIONS
-h, --help print this message and exit

:param: mynetwork the base of an ftbl file (mynetwork.ftbl)

:returns: mynetwork.xgmml -- file of the network definition suitable for cytoscape
