The Event Notify Test Runner is a general purpose Unix utility intended to make rapid feedback and automated testing natural and completely ordinary.

Some graphical applications such as the PostScript/PDF viewer gv ship with a -watch option with reloads the document whenever the source file is modified. This is useful, but it is even better for applications to provide a programmatic means of refreshing the display. The browser add-on LiveReloadhas attempted to solve this problem for web developers by injecting JavaScript that listens on a web socket. The solution should not be this complex, indeed this is all that is required
