+      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.
