%description
Given a list of substance compositions, a list of substances involved in a
process, and a list of constraints in addition to mass conservation of
elementary constituents, the package contains functions to build the
substance composition matrix, to analyze the uniqueness of process
stoichiometry, and to calculate stoichiometric coefficients if process
stoichiometry is unique. (See Reichert, P. and Schuwirth, N., A generic
framework for deriving process stoichiometry in enviromental models,
Environmental Modelling and Software 25, 1241-1251, 2010 for more
details.)
