Tail Implementation In Python (wrapper for *nix tail)
Written to demonstrate how to write a cross platform tool that executes long running sub processes and capturing stderr and stdout in separate code paths for handling in python.
This implementation is non-blocking and thus will not interrupt the tool creating or rotating the log file.
To get tail for windows that works with this demo, see: https://github.com/JavaScriptDude/cygtail. This should work out of the box with Linux, BSD, Mac.
