there might be a commercial company which does this, i don't know. but AFAIK no open source project does this.
problem: how to track diverse version numbers in multiple open source projects which are used to build ports solution: a webpage hosted somewhere which has a open editable wiki which has fixed DISTNAME/PKGNAME (except for name changes), and allows editing the stable version numbers. (possibly changed HOMEPAGE or MASTER_SITE) i.e devel->geotiff->1.4.0 (right now the geotiff version in -current is 1.3.0) there are just too many ports, and too many version changes, and too few people. and ports are ever-growing. this allows interested porters to parse the webpage such that we can 1) quickly know which ports are lagging behind 2) can do a quick make fetch and make makesum this is openbsd specific only. any interest in this?
