Comment(by cremona):
One reason the docstrings are long is that I was asked (e.g. on this
ticket) to give an explanation. So please do not now ask me to shorten
them. As for references, as I have already said, there is an old
unpublished preprint by me and Mark Watkins, which has now been superceded
(we now use better models), and there will be a PhD thesis by Kimi
Tsukazaki, but he has not written it yet. I hope you are not suggesting
that the code cannot be accepted into Sage until his thesis has been
written and examined and passed? On the contrary, I was hoping that the
code based on his thesis (which includes many more prime l as I have
already said) would be accepted into Sage -- on its merits because it
works -- before he submits the thesis.
I feel I am going round in circles here. This ticket was created because
the old code was causing an unnecessary delay in Sage startup time, and
the patch fixes that, and clarifies how the code works at the same time.
