[seqfan] Re: Suggested keyword: veri

[Alonso Del Arte]

I agree a hundred percent with Hugo that we need to get in the habit
of taking advantage of the existing mechanism to record info about
verification: how it was done, for what values, with what tool, etc.
Even if none of us verify sequences systematically, I bet a lot of us
wind up doing some sort of verification of existing sequences when we
submit new sequences or comments.

It occurs to me today that when it comes to multiplicative sequences
(keyword:mult) the verifier could also say something like "Verified
sequence is [fully] multiplicative for the values shown here."
