-----------------------------+----------------------------
In sage/libs/ratpoints there is a cython interface to the standard
ratpoints package (Michael Stoll's efficient C library for point searching
on curves of the form {{{y^2=f(x)}}} for polynomials {{{f(x)}}} of any
degree).
The interface currently only allows the user to specify the coefficients
of the polynomial, a height bound, and a maximum number of points to be
found. But ratpoints has other parameters, in particular upper and lower
bounds for the denominator of {{{x}}} (useful in searching for
integralpoints) and the ability to search only for {{{x}}} in one or more
real intervals.
We propose to enhance the interface to allow non-defaults for all the
ratpoints parameters, while remaining completely backwards compatible.
