I like the independent-of-pkg approach, and the idea of running the script just before is a good idea. At https://cgit.freebsd.org/ports/tree/security/periodic-filter-vuxml/files/400.filter-vuxml.in#n80 how does that for-loop work? I had anticipated some kind of xml / perl script for that. This seems to be entirely bourne shell. What magic is that? -- Dan Langille [email protected]
