funny, i was thinking about something like this today. manually downloading/installing libraries is annoying for the programmer, and when they want to release their program they have to either package the libraries or tell people they have to download additional things
instead, it would be nice if the libraries were automatically downloaded the first time they are encountered, so that the programmer could just distribute their file(s)
linux does packaging thingies now... though i haven't used linux in a few years so i dunno how it works. we can allow the programmer to not only specify a library, but also a hash to make sure it's the precise desired file
