+projects.  It allows you to use the power of Lisp (Guile Scheme) to define
+your tasks, build steps, repetitive tasks or other automation.
+
+With Maak you can easily call external shell commands and integrate with
+your existing scripts and tools.  It is inspired by the GNU Make utility
+but it does away with a lot of the complexity that comes with its history.")
