I cannot find a good, complete description of what a vector or slack package should include, or what should, must, or may be in each of the files.
I'm hoping someone can point one out to me. Failing that, it's long past time to put those docs together. I'm thinking at least some pages for man 5 and of course pages for VL HelpCenter.
Time prevents me doing much, but this one's so fundamental I'll do all I possibly can.
