+       "With lispy syntax, shortcuts, and improvements, LASS aims to help you
+out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS
+supports two modes, one being directly in your lisp code, the other in pure
+LASS files.
+
+LASS works on the following simple principles: A list is a block. The first
+argument in the list is a selector. The body of the list makes up the
+properties and sub-blocks. A property is started with a keyword that is used
+as the property name. Following is a bunch of property arguments until a new
+keyword, list, or the end is reached. A list inside a block is, again, a block
+with the twist that the parent block's selector is prepended to the
+sub-block's selector.")
