Introduction
The pipe2py package can compile a Yahoo! Pipe into pure Python source code, or it can interpret the pipe on-the-fly. It supports embedded pipes too.

pipes-engine uses pipe2py to run your Yahoo! Pipes on Google’s servers. It retrieves and stores Yahoo! Pipes definitions, compiles them to Python and then runs them when requested on Google's App Engine.
