+You may want to jump straight to the TUTORIAL file, or perhaps watch the task
+movie on YouTube:

+  http://?????????????????
+
+Either will give you a fairly good idea of what task is capable of, and whether
+it fits in to your way of working.  As a command line application, task is not
+for everyone and some of you may prefer to not proceed.  The movie or TUTORIAL
+file are the quickest way for you to make that decision.
+
+Task is based on ideas presented in the todo.sh script, found on:
+
+  http://todotxt.org
+
+Task has a few more features than todo.sh, but fundamentally, they are both
+working toward the same goals, which is to help you follow basic Getting Things
+Done (GTD) principles.
+
+All feedback is welcome, in addition to any bug reports or patches to:

+Got an idea for an enhancement?  Send an email!
