When flint
is updated, it can ship new built-in rules. update_flint()
will
automatically add those new rules in the flint/rules
folder. New rules are
only determined by their names and rules that already exist in flint/rules
are not affected.
For instance, if you added a custom rule use_paste.yml
, then it will never
be removed by update_flint()
, even if flint
later adds a built-in rule
also named use_paste.yml
.
