The cs:~juju-qa/precise/juju-reports charm follows this general
pattern, but there are some specialized hooks: install, start, stop
and upgrade-charm.

config-changed, database-relation-broken, database-relation-changed,
database-relation-departed, and website-relation-changed are all the
same code and read the state afresh every time without reference to
the script name.

The charmworld charm is similar.
