+## LiveScript Jakefiles
+
+Jake can also handle Jakefiles in LiveScript. Be sure to make it Jakefile.ls so Jake knows it's in LiveScript.
+
+Here's an example:
+
+```livescript
+require! \util
+
+desc 'This is the default task.'
+task \default, (params) !->
+  console.log 'This is the default task.'
+  console.log (util.inspect arguments)
+  jake.Task[\new].invoke []
+
+task \new !->
+  console.log 'ello from new'
+  jake.Task[\foo:next].invoke [\param]
+
+namespace \foo ->
+  task \next (param) !->
+    console.log "ello from next with param: #param"
+```
