They are stub rules that control the alerting functionality of
preprocessor alerts. So, for example ...


alert ( msg: "STREAM5_DATA_WITHOUT_FLAGS"; sid: 11; gid: 129; rev: 1;
metadata: rule-type preproc ; classtype:protocol-command-decode; )

Would enable the alerting of the stream5 without flags alert.

Each alerting preproc should have a readme which describes the alerts
associated with it. In addition the gen-msg.map should give you a list
if preprocessor gids along with their associated sids.


Cheers,
Justin
