| This module matches at a limited rate using a token bucket filter. |
| A rule using this extension will match until this limit is reached |
| (unless the `!' flag is used). It can be used in combination with the |
| .B LOG |
| target to give limited logging, for example. |
| .TP |
| .BI "--limit " "rate" |
| Maximum average matching rate: specified as a number, with an optional |
| `/second', `/minute', `/hour', or `/day' suffix; the default is |
| 3/hour. |
| .TP |
| .BI "--limit-burst " "number" |
| Maximum initial number of packets to match: this number gets |
| recharged by one every time the limit specified above is not reached, |
| up to this number; the default is 5. |
