Note:
There are no "community" rules available anymore (since snort > 2.4), so
it makes no sense to install the old rules!
If someone needs the official Snort rules from Sourcefire he/she has to
install them from cmdline or through the supplied tools.
It is up to the final user to decide what kind of rules he/she wants to
use ("Subscriber Release" or "Registered User Release").
Further infos about the official Snort rules can be found here:
http://www.snort.org/snort-rules
As a replacement for the former community rules we should package the open
rulesets from emergingthreats.net which are available under the terms of the
GPL: http://rules.emergingthreats.net/open/
