Nailgun is a client, protocol, and server for running Java programs from the command line without incurring the JVM startup overhead.
Programs run in the server (which is implemented in Java), and are triggered by the client (written in C), which handles all I/O.
Use
gradle clean installDist
to build the application from source. You'll find the result in
build/install/nailgun
