computer rant
It's amazing and appalling just how many questions for "how to get <computable almanac data> in bash" wind up being "just use curl on <website> and parse that data" answers.

I have a computer.
It's pretty good at computing.
I don't want to depend on someone else's computer, that might get turned off at any time, and that's only reachable by an often crappy 'Net connection.
