- * \file
- *
- * \author Victor Julien <victor@inliniac.net>
- *
- * Implements per flow bits. Actually, not a bit,
- * but called that way because of Snort's flowbits.
- * It's a binary storage.
- *
- * \todo move away from a linked list implementation
- * \todo use different datatypes, such as string, int, etc.
- * \todo have more than one instance of the same var, and be able to match on a
- * specific one, or one all at a time. So if a certain capture matches
- * multiple times, we can operate on all of them.
