Command lnsrv (line server) is an HTTP server that serves input lines. The lines can be used to distribute labor to worker jobs using simple HTTP requests.
Each request to / returns the next line in a synchronous manner. When the
input lines run out, a customizable end-string is emitted. The server can be
configured to shut down after N end-strings.
Command line flags:
-end string
String to send when no more lines are available. (default "END")
-f string
File to read from. (default stdin)
-n uint
Number of ENDs to send before exiting. (default infinite)
-port uint
Port to listen on. (default 7777)
