scripts for checking naming conventions (prefix etc) for PL/SQL

Hi!
I'm looking for scripts that can validate PL/SQL code against
some business coding style rules.

Checking that procedure start with
insert/update/delete/check

that schema-prefix is used,
that procedures not are too long
and other nice things to check.
I read about it somewhere, but I can't remember where I read it.

The scripts are not so important, it's more important for me to get some
ideas about
what could be of value to check.
Thaks for help!
