+Cassowary is an incremental constraint solving toolkit that
+efficiently solves systems of linear equalities and inequalities.
+Constraints may be either requirements or preferences. Client code
+specifies the constraints to be maintained, and the solver updates the
+constrained variables to have values that satisfy the constraints.
+Version 0.50 of the solving toolkit adds support for a one-way finite
+domain subsolver.
+
+A technical report is included in the distribution that describes the
+algorithm, interface, and implementation of the Cassowary solver.
+Additionally, the distribution contains toy sample applications
+written in Smalltalk, C++, Java, and Python, and a more complex
+example Java applet, the "Constraint Drawing Application".
