apt-got is a customizable mirror engine. It works like a highly specialized proxy. It employs several pluggable modules that are customized for specific jobs. The first available module builds and supervises a partial (or full) Debian mirror which is populated on-the-fly by apt-get requests. There is also a simple mirror module that can be used to mirror source directories or even (static) Web pages. For increased performance on already-cached files, it employes its own Apache module. It supports customized mirroring algorithms.
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.
