Comment 2 for bug 1202442

AIUI, that presents a bootstrap problem (writing a non-trivial amount of code to grab charm-helpers to use with the rest of the hooks. IIRC there is a bug with a discussion about this within charm-helpers (and the larger juju community), with the current recommendation to just ship the library within the charm. If this thinking changes in the future, I'd be happy to revisit the charm.
