It seems like it would be good to document the “update all of my global packages” functionality in jetpack -h.

Hey @jasikpark, this is already part of the line above, as [<package>...] means they are optional.

ah, ok. that wasn’t clear to me, but I’m not sure how to make [] signify “optional” to anyone who doesn’t know that already
