- * Sample server that just keeps first available window mapped.
- *
- * It also reads and echos anything that happens on stdin as an
- * example of tracking events from sources other than miniglx clients.
- *
- * It reads & writes without blocking, so that eg. piping a lot of
- * text to stdin and then hitting 'ctrl-S' on the output stream won't
- * cause it to stop handling miniglx events.
- *
- * See select_tut in the linux manual pages for a good overview of the
- * select(2) system call.
