+# Sample verbose configuration file for Unicorn (not Rack)
+#
+# This configuration file documents many features of Unicorn
+# that may not be needed for some applications. See
+# http://unicorn.bogomips.org/examples/unicorn.conf.minimal.rb
+# for a much simpler configuration file.
+#
+# See http://unicorn.bogomips.org/Unicorn/Configurator.html for complete
+# documentation.

+# run on the standard HTTP port (80), there is no reason to start Unicorn
+# as root unless it's from system init scripts.
+# If running the master process as root and the workers as an unprivileged
+# user, do this to switch euid/egid in the workers (also chowns logs):
