ape is a make/rake/ant/fab-like system with support for FOSD.
ape is short for "A Productive Environment". It provides a way to organize tasks in feature modules. Feature modules can introduce new tasks and refine tasks that have been introduced by other features.
Tasks are defined as simple python functions. ape makes these task functions available from the command line and provides usage information by extracting the functions' docstrings.
ape can be used to manage software product lines(SPL). SPLs are placed in containers that contain their features and products.
