Thanks for the extra explanations, Bill.
I wrote an extra item in pari's online FAQ, and an additional note in
the manual, while Karim has put into the pari cvs already. But (at
least as far as mwrank is concerned) we still need a "proof=true"
version of factorint().

factor is a general factoring function for integers, polynomials and
various other types. It also takes an optional parameter to tell it
how many primes to use in the factorisation. So for example if you
want to know all prime factors of an integer up to 1000 you'd use
factor(n, 1000).
factorint
factorint and factor is not the same thing. factorint allows you to
specify various parameters for the factorisation. For example you can
select which of the various factorisation algorithms are used by Pari
to split your integer. You can also pass an integer to the factor
functions telling you up
