This is an improved version of the Unix 'yes' command. Some programs never quit if the standard input continues to feed data. This program adds the number of seconds to fire to limit how long this program will continue in a loop. Also it has a firing rate option if that is desired.
Usage: yeah [-r <rate>] [-s <duration>] [STRING]
-r {seconds} the firing rate in seconds. E.g. -r 0.5
-s {seconds} the number of seconds to fire. Default is infinity.
-h display this help and exit.
