 SBT extras defines a simplified task DSL for those who are defining simple tasks that do not need to be relied upon, or you are unsure and can refactor later.   Once including the sbt-extra-plugin, all you have to do is place the following in your build.sbt to create tasks:

 The DSL currently supports between 2 and 9 dependencies.  The DSL does not allow defining tasks on different configurations, although this will be added shortly.

+### Simple Setttings
+
+SBT distinguishes between defining Setting and Tasks through the `apply` and `map` methods.   The Simple DSL has no such distinction.   Defining a setting is as easy as:
+
+    simple_setting("name") is "project-name"
+
+Settings can also depend on other settings.
+
+    simple_setting("name") on (version) is { v => "project-name" + v }
+
+Since a Setting can *only* be defined using other settings, attempting to use a non-setting in the on calls results in a type error.
