[Logs-devel] add cl-interpol to LoGS?

Hi all,

I'm starting to make a lot of use of Edi Weitz' excellent cl-interpol 
package (you have another winner, Edi!) in my LoGS rulesets.  I'm 
wondering if its functionality is generally useful enough (the way that 
cl-ppcre is) to warrant adding to LoGS.

I'm doing things like:

;; the regexp that defines the internal network
(defvar *internal-network-ipv4-regexp* "10.3.\\d+.\\d+")

;; there is no action, so throw away internal login messages
(rule named 'ignore-internal-logins-ipv4
          matching regexp 
#?"sshd\\[\\d+\\]: Accepted publickey for .* from 
${*internal-network-ipv4-regexp} port \\d+ ssh2")

That basically allows me to more easily share rulesets with other shops; 
They can define their own *internal-network-ipv4-regexp* and use my rules.

What do you think?
