Hierarchical Configuration is a Python library that is able to take a running
configuration of a network device, compare it to its intended configuration,
and build the remediation steps necessary bring a device into spec with its
intended configuration.

Hierarchical Configuration has been used extensively on:

* Cisco IOS
* Cisco IOSXR
* Cisco NXOS
* Arista EOS

However, any NOS that utilizes a CLI syntax that is structured in a similar
fashion to IOS should work mostly out of the box.

NOS's that utilize a set based CLI syntax has been added as experimental
functionality. OS's that utilize this syntax are:

* Juniper JunOS
* VyOS
