INTRODUCTION

    This is a very simple abstraction for accessing facter facts. Facter is a
    simple key=value interface to many system facts. The value is currently
    only a string type.

    Facter was 1.16 at the time of writing.

    Gathers the facts into a singleton (to avoid multiple lengthy calls to
    facter). Adds support for filtering. Returns a dictionary containing keys.


        from pyacter.facter import Facter
        import pprint
        import re

        class MyFacter(Facter):
            def facts(self):
                return super(MyFacter, self).facts(key_filter=self.my_filter)

        class ThingFacts(MyFacter):
            my_filter=[
                re.compile(r"^kernel"),
                re.compile(r"^inter"),
                re.compile(r"someprefix_"),
                re.compile(r"someotherprefix_"),
            ]


        if __name__ == "__main__":

            thing_facter = ThingFacts()

            pprint.pprint(thing_facter.facts())

        $ PYTHONPATH=. python example/example.py 
        {'interfaces': 'lo0,gif0,stf0,en0,p2p0',
         'kernel': 'Darwin',
         'kernelmajversion': '11.4',
         'kernelrelease': '11.4.0',
         'kernelversion': '11.4.0'}
