"flintqs" is Bill Hart's quadratic sieve code, as packaged for use in  
SAGE. It's a routine for factoring huge integers. It's already  
available in SAGE using the qsieve() function.

But this has nothing to do with univariate polynomials as such.

There is a larger project called FLINT, which has not yet been  
released. Bill Hart and I are the authors. The quadratic sieve will  
be a component, when it is released. The other component will be  
univariate polynomial arithmetic over Z. (Not Q.)

Work on the polynomial arithmetic slowed down a while ago because we  
both got distracted by other things. But recently we have found more  
time, and development is coming along nicely.

I might be persuaded to do a short talk on the current state of FLINT  
at SD4. I am also considering spending some time at SD4 on starting  
to develop a patch to wrap the polynomial arithmetic in SAGE. I don't  
expect it to be done by the end of SD4, but it might be feasible to  
at least start getting a patch that I can maintain as FLINT matures,  
until the time is ready to actually bring it into SAGE.
