Restarting a script automatically when modified

Node-dev is a development tool for Node.js that automatically restarts the node process when a script is modified.

With node-dev you don't have to manually specify which files should be watched nor do you have to deal with ignore lists for files that should be excluded. This is done using a thin wrapper script that hooks into the require() function as well as into several methods of the VM module to determine which files need to be monitored.

This does not only work for .js files, but also for .json or .node or .coffee files or any other custom extension that has been added to require.extensions.

Another great benefit of this zero-config approach is that it doesn't cause any unnecessary restarts when for example client-side only scripts are modified.
