+ * This backend presents a fake printer that will choose the first

+ *
+ * Option failover contains a comma separated list of IPP URIs. The
+ * URIs are attempted in-order.
+ *
+ * Option failover-retries contains an integer that indicates how many
+ * times to iterate through the failover list before completely
+ * failing.
+ *
+ * Contents:
+ * main() - Checks each printer in a failover list, and
+ * sends job data to the first available printer
+ * move_job() - Sends and IPP Move-Job request
+ * check_printer() - Checks a printer's attributes to see
+ * if it's enabled and accepting jobs
+ * read_config() - Read the backends configuration from
+ * options
+ * get_printer_attributes() - Sends an IPP Get-Attributes request to
+ * a URI
+ * sigterm_handler() - Handle SIGTERM that cancels the job
+ * password_cb() - Password call back used to disable password
+ * prompt
