Pants Build System
Pants is a scalable build system for monorepos: codebases containing multiple projects, often using multiple programming languages and frameworks, in a single unified code repository.
Some noteworthy features include:
- Explicit dependency modeling.
 - Fine-grained invalidation.
 - Shared result caching.
 - Concurrent execution.
 - Remote execution.
 - Unified interface for multiple tools and languages.
 - Extensibility and customizability via a plugin API.

We release to PyPI  
We use Travis CI to verify the build .
Requirements
To run Pants, you need:
- Linux or macOS.
 - Python 3.6+ discoverable on your 
PATH. - A C compiler, system headers, Python headers (to compile native Python modules) and the 
libffilibrary and headers (to compile and link modules that use CFFI to access native code). - Internet access (so that Pants can fully bootstrap itself).
