# Fact: is_pe, pe_version, pe_major_version, pe_minor_version, pe_patch_version
#
# Purpose: Return various facts about the PE state of the system
#
# Resolution: Uses a regex match against puppetversion to determine whether the
#   machine has Puppet Enterprise installed, and what version (overall, major,
#   minor, patch) is installed.
#
# Caveats:
#
