#   There are also several undocumented settings.
#
# @note
#   For Red Hat based systems, ensure that you meet the minimum requirements described in the passenger docs.
#
# The current set of server configurations settings were taken directly from the Passenger Reference. To enable deprecation warnings 
# and removal failure messages, set the passenger_installed_version to the version number installed on the server.
#
# Change Log:
#   - As of 08/13/2017 there are 84 available/deprecated/removed settings.
#   - Around 08/20/2017 UnionStation was discontinued options were removed.
