The show-node-objects script

This script accepts a host name and produces a list of objects in manifest syntax associated with that host. It is meant to be run on the puppetmaster host. By default only the 'hostname' fact is supplied but other facts can be specified by using the '--fact` option (multiple times if needed). If the argument to '--fact' does not contain a '=' sign it is interpreted as a file containing facts in YAML format as output by 'facter --yaml'.
