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.

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.

Tup's manual and informational site can be found at http://gittup.org/tup.

Again on build systems. Let's talk about complete correctness

Recently I tried tup and I am VERY impressed by its correctness and speed, and the fact that monitoring the file system makes the tool really robust. It is also very easy to understand. It never gets anything wrong, and when it does, it will show…
