Puppet - How to list facts in facter in Puppet

Was messing around puppet and trying to get a list of "facts". Google & searching on puppet labs didn't return any luck. Most of the search result points to bug reports.

With no luck at all, I gotta skim through the docs to find the list of facts for my new toy (puppet). Stumble this link that actually points where the light is.

In short, to list the facts of puppet, do this in command line :
facter  | less

Hopefully this post will shed some light onto people searching on how to list facts in puppet.

Ciao !!!
