When distfiles have to be ignored, whether for specific versions, or specific minor revisions. For example, to exclude version 8.2 from distfile version checks because it is known to be broken, add:

PORTSCOUT=	ignore:8.2

When specific versions or specific major and minor revisions of a distfile must be checked. For example, if only version 0.6.4 must be monitored because newer versions have compatibility issues with FreeBSD, add:

PORTSCOUT=	limit:^0\.6\.4

When URLs listing the available versions differ from the download URLs. For example, to limit distfile version checks to the download page for the databases/pgtune port, add:

PORTSCOUT=	site:http://pgfoundry.org/frs/?group_id=1000416
