# Definition: augeas::lens
#
# Deploy an Augeas lens (and its test file).
# Check the lens (and run the unit tests) automatically and remove the files if
# the checks fail.
#
# Parameters:
# ['ensure'] - present/absent
# ['lens_content'] - the content of the lens
# ['lens_source'] - the source for the lens
# ['test_content'] - optionally, the content of the test
# ['test_source'] - optionally, the source for the test file.
# ['stock_since'] - optionally, indicate in which version of Augeas
# the lens became stock, so it will not be deployed
# above that version.
#
# Example usage:
#
# augeas::lens { 'networkmanager':
# lens_content => file('networkmanager/lenses/networkmanager.aug'),
# test_content => file('networkmanager/lenses/test_networkmanager.aug'),
# stock_since => '1.0.0',
# }
#
