  * This is useful, for example, when running in a Docker container.
  *
+ * DETAILED RULES:
+ *   - If the environment variable is set to the string "true" or "false", the
+ *     value becomes Boolean true or false.
+ *   - If the environment variable is set to the string "null", the value
+ *     becomes null.
+ *   - If the environment variable is set to the string "undefined", the setting
+ *     is removed entirely, except when used as the member of an array in which
+ *     case it becomes null.
+ *   - If the environment variable is set to a string representation of a finite
+ *     number, the string is converted to that number.
+ *   - If the environment variable is set to any other string, including the
+ *     empty string, the value is that string.
+ *   - If the environment variable is unset and a default value is provided, the
+ *     value is as if the environment variable was set to the provided default:
+ *       - "${UNSET_VAR:}" becomes the empty string.
+ *       - "${UNSET_VAR:foo}" becomes the string "foo".
+ *       - "${UNSET_VAR:true}" and "${UNSET_VAR:false}" become true and false.
+ *       - "${UNSET_VAR:null}" becomes null.
+ *       - "${UNSET_VAR:undefined}" causes the setting to be removed (or be set
+ *         to null, if used as a member of an array).
+ *   - If the environment variable is unset and no default value is provided,
+ *     the value becomes null. THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF
+ *     ETHERPAD; if you want the default value to be null, you should explicitly
+ *     specify "null" as the default value.
+ *
  * EXAMPLE:
  *    "port":     "${PORT:9001}"
  *    "minify":   "${MINIFY}"
