+Pyomo is a Python-based open-source software package that supports a diverse
+set of optimization capabilities for formulating and analyzing optimization
+models.
+
+Modeling optimization applications is a core capability of Pyomo. Pyomo can be
+used to define symbolic problems, create concrete problem instances, and solve
+these instances with standard solvers. Thus, Pyomo provides a capability that is
+commonly associated with algebraic modeling languages such as AMPL, AIMMS, and
+GAMS, but Pyomo's modeling objects are embedded within a full-featured
+high-level programming language with a rich set of supporting libraries. Pyomo
+supports a wide range of problem types, including:
+* Linear programming
+* Quadratic programming
+* Nonlinear programming
+* Mixed-integer linear programming
+* Mixed-integer quadratic programming
+* Mixed-integer nonlinear programming
+* Mixed-integer stochastic programming
+* Generalized disjunctive programming
+* Differential algebraic equations
+* Bilevel programming
+* Mathematical programming with equilibrium constraints
