Variables are promises that can be defined in any promise bundle. Users can create their own [variables][Variables].
To see variables defined on a particular host during pre-evaluation run
cf-promises --show-vars as a privileged user. To see all variables defined
over the course of an agent execution run cf-agent --show-evaluated-vars. Note
cf-promises shows variables resolved during pre-evaluation while cf-agent can
show variables resolved during actual execution where the system may be
modified.
See Classes for an explanation of the tags.
