+programming problems (LPs) based on an advanced implementation of the primal
+and dual revised simplex algorithm.  It provides special support for the exact
+solution of LPs with rational input data.  It can be used as a standalone
+solver reading MPS or LP format files via a command line interface as well as
+embedded into other programs via a C++ class library.")
