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 (C and Python clients available), which handles all I/O. This project contains the SERVER ONLY.

There is a newer version: 1.0.1
