Tup 0.7.3-18-g8e63ea4

A command line file-based build system

Tup is a file-based build system for Linux, OSX, and Windows. It inputs a list of file changes and a directed acyclic graph (DAG), then processes the DAG to execute the appropriate commands required to update dependent files. Updates are performed with very little overhead since tup implements powerful build algorithms to avoid doing unnecessary work. This means you can stay focused on your project rather than on your build system.

You can use Tup anywhere you would use another build system (like make, or any of its derivatives). One reason you would want to use tup is if you like to update things very quickly. For example, if you typically execute a build in a subdirectory because it takes too long to figure out what to do when you execute the build from the top, you might want to look into tup.
