Description:

The Systems Biology Markup Language (SBML) is a computer-readable format for
representing models of biochemical reaction networks. SBML is applicable
to metabolic networks, cell-signaling pathways, genomic regulatory networks,
and many other areas in systems biology.

LIBSBML is a C application programming interface (API) library for reading,
writing and manipulating the SBML. Currently, the library supports all of
SBML Level 1 Version 1 and Version 2, and nearly all of SBML Level 2 Version 1.
(The still-unimplemented parts of Level 2 are support for RDF and support
for MathML's semantics, annotation and annotation-xml elements.
These will be implemented in the near future.)
