CheXpy is an easy-to-use utility for developers who use Microsoft(R) Visual SourceSafe. In the modern development environment the same source files could be used simultaneously by several developers, and immediate acknowledgement that the file has been checked in/out is essential. CheXpy makes it easy to keep the track of check in/out operations by monitoring VSS database routinely. Monitoring SourceSafe with CheXpy is really intuitive and easy. Once you start up the program you can instruct CheXpy to keep an eye on source files of your interest.
