A good number of the rules have a references field. This maps to
information about the rule.
The reason packets are flagged is because they match the rule and the
reason the rule was written is often described in the refernces
SnortSnart parses them and provides links or you can look at
#define BUGTRAQ_URL_HEAD "http://www.securityfocus.com/bid/"
#define CVE_URL_HEAD "http://cve.mitre.org/cgi-bin/cvename.cgi?name="
#define ARACHNIDS_URL_HEAD "http://www.whitehats.com/info/IDS"
#define MCAFEE_URL_HEAD "http://vil.nai.com/vil/dispVirus.asp?virus_k="
#define URL_HEAD "http://"

Don't use a big word where a diminutive one will suffice.
