portupdate-scan simplifies dealing with /usr/ports/UPDATING when you have so many ports installed that it is difficult to know which sections are relevant. It reads /usr/ports/UPDATING, attempting for each block to determine whether the affected ports are installed. It omits blocks that do not apply. It handles wildcards and other special cases, however it cannot handle all variants of phrases used on the AFFECTS: line. In uncertain cases, it errs on the side of reporting. Alex Stangl
