Mike Thank you for taking the time to write such a detailed explanation. Unfortunately, dunce that I am, I didn’t understand most of it. I’m just a tool user and have little understanding of the code behind the tools that I use.
When I see something like this:
reinplace "s|@PREFIX@|${prefix}|g" ${worksrcpath}/scripts/logwatch.pl
My head spins.
Am I supposed to actually do all that stuff that I see when I run port cat
logwatch?
Sorry for my ignorance.
Mike
