338 This is a class that gives access to the configured fact provider such as
339 MCollectives::Facts::Facter that uses Reductive Labs facter
340 </p>
341 <p>
342 The actual provider is pluggable and configurable using the
343 &#8216;factsource&#8217; configuration option.
344 </p>
345 <p>
346 To develop a new factsource simply create a class under
347 MCollective::Facts:: and provide the following classes:
348 </p>
349 <pre>
350   self.get_fact(fact)
351   self.has_fact?(fact)
352 </pre>
353 <p>
354 You can also just inherit from <a
355 href="Facts/Base.html">MCollective::Facts::Base</a> and provide just the
356 </p>
357 <pre>
358   self.get_facts
359 </pre>
360 <p>
361 method that should return a hash of facts.
