Comment(by mhampton):
For PPL, I was using ppl_lcdd. It accepted my input file with 'real'
input specified, and on linux the output was correct in the sense of being
equivalent to cddlib's to the lower precision. I haven't checked the
correctness of the OS X output, just noticed it was different.
For numerical input I'd like to test Qhull and if it performs better we
might want to make it the default for numerical polyhedra.
