+Cantera is a suite of object-oriented software tools for problems involving
+chemical kinetics, thermodynamics, and/or transport processes.
+
+Cantera provides types (or classes) of objects representing phases of
+matter, interfaces between these phases, reaction managers, time-dependent
+reactor networks, and steady one-dimensional reacting flows. Cantera is
+currently used for applications including combustion, detonations,
+electrochemical energy conversion and storage, fuel cells, batteries, aqueous
+electrolyte solutions, plasmas, and thin film deposition.
+
+Cantera can be used from Python and Matlab, or in applications written
+in C++ and Fortran 90.
