# Fact: augeasversion
#
# Purpose: Report the version of the Augeas library
#
# Resolution:
#   Loads ruby-augeas and reports the value of /augeas/version, the version of
#   the underlying Augeas library.
#
# Caveats:
#   The library version may not indicate the presence of certain lenses,
#   depending on the system packages updated, nor the version of ruby-augeas
#   which may affect support for the Puppet Augeas provider.
#   Versions prior to 0.3.6 cannot be interrogated for their version.
