#  Phusion Passenger Standalone uses a template file to
#  generate an Nginx configuration file. The original template
#  file can be found by running the following command:
#
#    ls $(passenger-config about resourcesdir)/templates/standalone/config.erb
#
#  You can create a copy of this template file and customize it
#  to your liking. Just make sure you tell Phusion Passenger Standalone
#  to use your template file by passing the --nginx-config-template
#  parameter.
#
#  *** NOTE ***
#  If you customize the template file, make sure you keep an eye
#  on the original template file and merge any changes.
#  New Phusion Passenger features may require changes to the template
#  file.
