I was professionally writing Ruby code as that community struggled
through package issues. I hope that experience can shed some light
here. Also I'd like to understand the basic use cases and how they work
As a user, here are my 2 use cases:
1. My friend tells me about awesome library X, and I want to install it
and use it. Planet2 makes this easy.
2. I have an existing app running and I want to replicate it exactly
somewhere else (including libraries). I'm not sure this is possible
with raw Planet2. The Ruby community finally dealt with this by saving
the full library dependency list in a file ("bundle", with version
numbers) that you save alongside your app. It works fairly well.
Their experience suggests that accidental backwards incompatible changes
in libraries happen frequently enough to need some kind of support for.
Compatibility with the core language was not supported. Either a
library's webpage would say "requires ruby core >= 1.8.x", or sometimes
importing the library would produce an error message telling you the same.
Do these use cases make sense? (I'd like to hear about library
developer use cases, but I have no experience there)
