netstiff (formerly known as webdiff) is a powerful Web and FTP site update checker. It supports a variety of different methods (diff, HTML, size, date, MD5 sum, regexp) to check for updates. There are also sophisticated settings to make it useful for partly dynamic Web pages. Without any given arguments, netstiff will either run its interactive configuration tool or check your sites for updates and print the changes in a diff(1)-like manner.
AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
