+      A build system that uses ptrace to handle dependencies automatically
+    '';
+    longDescription = ''
+      Fac is a general-purpose build system inspired by make that utilizes
+      ptrace to ensure that all dependences are enumerated and that all
+      source files are added to a (git) repo. An important feature of fac
+      is that it automatically handles dependencies, rather than either
+      complaining about them or giving an incorrect build. Currently, fac
+      only runs on linux systems, but on those systems it is incredibly
+      easy to use!
