[rancid] Add new scripts for Netgear?

To whom it may concern,
I have been using RANCID for quite a few years and find it an invaluable tool
for peer review, etc and I'd like to expres smy gratitude to all the
developers.
I write in relation to a previous post:
http://www.shrubbery.net/pipermail/rancid-discuss/2008-April/003037.html
and I have CC'd the author. I can additionally confirm that Ed's script also
works for Netgear GSM7224.
I attach his scripts again as I needed to remove some HTML formatting.
I'd love to see these added to RANCID as well as the change to rancid-fe:
# diff rancid-fe~ rancid-fe
45a46
> elsif ($vendor =~ /^netgear$/i) { exec('grancid', $router); }
I'm happy to help clean/edit/format the scripts to this end.
Can someone advise me as to what is required to see this happen?
Thanks,
Barry O'Donovan
