Hi All,
I would like to propose a small improvement to "factor" help message:
indicate factor capabilities and in particular maximum input size. As
it depends on how factor has been compiled (with or without GMP
library), I propose the attached patch.
I think it is very useful to know on a given system how factor has
been compiled by the distribution.
What do you think of that ?
Best regards
