Waf is a Python-based framework for configuring, compiling and installing applications. Here are perhaps the most important features of Waf: * Automatic build order: the build order is computed from input and output files, among others * Automatic dependencies: tasks to execute are detected by hashing files and commands * Performance: tasks are executed in parallel automatically, the startup time is meant to be fast (separation between configuration and build) * Flexibility: new commands and tasks can be added very easily through subclassing, bottlenecks for specific builds can be eliminated through dynamic method replacement * Extensibility: though many programming languages and compilers are already supported by default, many others are available as extensions * IDE support: Eclipse, Visual Studio and Xcode project generators (waflib/extras/) * Documentation: the application is based on a robust model documented in The Waf book and in the API docs * Python compatibility: cPython 2.4 to 3.4, Jython 2.5, IronPython, and Pypy
