Response is a set of tools to handle automatic email responses, also called "Out of Office", "Vacation", or "Autoreply" messages. Response tries hard to do that the correct way, i.e. not responding to messages that should not be responded to. All of the validation code can be easily modified to suite your needs, but the project tries hard to ship sane defaults. It is designed for many virtual users and multiple mail servers, but works just fine for small deployments. Configuration and response state is stored in an RDBMS.
tsf is a command line utility for creating timestamped copies of files. When invoked on a file, a copy of that file is created with a name made of the file name plus a timestamp. When invoked again on the same timestamp mark, a copy with a timestamp plus a sub-index is created, and so on. tsf provides an easy and quick way for creating timestamped copies of files before modifying them.
