Nice, thanks! I read up on this and even ended up doing a successful C++ implementation, mostly based on http://www.cplusplus.com/forum/lounge/82407/. I'm not sure why anyone would want any other method than this, given that it returns all real/complex roots quite quickly and without any initial estimate or bracketing. > Use the init_session() function.

I tried: init_session(order='rev-lex',use_unicode=True,use_latex=True) var('t') t+t**2+1 and it prints 2 1 + t + t which is fine for the rev-lex thing but it is not the MathJax like display. What did you exactly mean by LaTeX pretty printing? The init_session help says: "use_latex: boolean or None; If True, use latex rendering if IPython GUI's". BTW in the same help, under order, there is no entry for rev-lex. It is not also clear that revlex, rev-lex both are accepted. Can you please update the docstring?
