juju-core 1.18.1-0ubuntu1 (i386 binary) in ubuntu trusty

 Through the use of charms, juju provides you with shareable, re-usable,
 and repeatable expressions of devops best practices. You can use them
 unmodified, or easily change and connect them to fit your needs. Deploying
 a charm is similar to installing a package on Ubuntu: ask for it and
 it’s there, remove it and it’s completely gone.
 .
 This package provides the client application of creating and interacting
 with Juju environments.
