File conversion

There are a couple of utilities converting polymake file format from and to other formats used by various useful software packages. These collections is currently very small, but it grows by demand.

lp2poly IN_FILE.lp >OUT_FILE.poly
Convert a linear programming problem given in LP-Format (as used by cplex & Co.) to polymake description and print it to stdout.
porta2poly IN_FILE.{poi,ieq} >OUT_FILE.poly
Convert a polyhedron file in porta input format (.poi or .ieq) to polymake description and print it to stdout.
poly2lp file
Convert a polymake description of a polyhedron to LP format (as used by CPLEX and other linear problem solvers) and write it to standard output.
