+A place to collect the various options that "can be passed to the
+underlying engine." Just kidding, they're constants and you can't
+change them. But this makes the user interface real simple.
+"""

+ABS_TOL = 1e-6
+"""
+The absolute tolerance used in all "are these numbers equal" and "is
+this number less than (or equal to) that other number" tests. The CVXOPT
+default is ``1e-7``, and we need a little bit of padding on top of that.
+"""
+
+
+FLOAT_FORMAT = '%.7f'
+"""
+The default output format for floating point numbers. It has been
+chosen to match the ``ABS_TOL``, in the sense that if ``x != y``,
+then they would not appear different when printed.
+"""
+
+
+VERBOSE = False
+"""
+The underlying CVXOPT solver can output debug information, and I
+guess, so could we. But we don't want to because it's ugly.
