+###               ejabberd configuration file
+###
+###
+
+### The parameters used in this configuration file are explained in more detail
+### in the ejabberd Installation and Operation Guide.
+### Please consult the Guide in case of doubts, it is included with
+### your copy of ejabberd, and is also available online at
+### http://www.process-one.net/en/ejabberd/docs/
+
+### The configuration file is written in YAML.
+### Refer to http://en.wikipedia.org/wiki/YAML for the brief description.
+### However, ejabberd treats different literals as different types:
+###
+### - unquoted or single-quoted strings. They are called "atoms".
+###   Example: dog, 'Jupiter', '3.14159', YELLOW
+###
+### - numeric literals. Example: 3, -45.0, .0
+###
+### - quoted or folded strings.
+###   Examples of quoted string: "Lizzard", "orange".
+###   Example of folded string:
+###   > Art thou not Romeo,
+###     and a Montague?
+
+###   =======
+###   LOGGING
+
+##
+## loglevel: Verbosity of log files generated by ejabberd.
+## 0: No ejabberd log at all (not recommended)
+## 1: Critical
+## 2: Error
+## 3: Warning
+## 4: Info
+## 5: Debug
+##
+loglevel: 4
+
+##
+## rotation: Describe how to rotate logs. Either size and/or date can trigger
+## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
+## does not disable rotation, it instead rotates the file and keeps no previous
+## versions around. Setting size to X rotate log when it reaches X bytes.
+## To disable rotation set the size to 0 and the date to ""
+## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf.
+## Some examples:
+##  $D0     rotate every night at midnight
+##  $D23    rotate every day at 23:00 hr
+##  $W0D23  rotate every week on Sunday at 23:00 hr
+##  $W5D16  rotate every week on Friday at 16:00 hr
+##  $M1D0   rotate on the first day of every month at midnight
+##  $M5D6   rotate on every 5th day of the month at 6:00 hr

+##
+## overload protection: If you want to limit the number of messages per second
+## allowed from error_logger, which is a good idea if you want to avoid a flood
+## of messages when system is overloaded, you can set a limit.
+## 100 is ejabberd's default.

+##   - "example.org"
+##
+hosts:
+  - "localhost"
+
+##
+## route_subdomains: Delegate subdomains to other XMPP servers.

+## to allow communication with an XMPP server called im.example.org.
