+tup (A file-based build system)
+Tup is a file-based build system for Linux, OSX, and Windows. It
+takes as input a list of file changes and a directed acyclic graph
+(DAG). It 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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
