From the developer:
PipeAlert is a utility that reads data from a Unix pipe and displays it in a floating Aqua window. The usefulness of such an application might not be obvious immediately, but it can be quite handy indeed, especially if used in conjunction with cronjobs. Of course there are other ways to accomplish the very same task, but none of them is as elegant as using PipeAlert.
You may want to check out more Mac applications, such as InsomniaT or IBM Performance Analysis Suite, which might be related to PipeAlert.
