-  #   filter(target=>source) => Filter
+  #   filter(source) => Filter
   #
   # Creates a filter that will copy files from the source directory into the target directory.
   # You can extend the filter to modify files by mapping <tt>${key}</tt> into values in each
   # of the copied files, and by including or excluding specific files.
   #
   # A filter is not a task, you must call the Filter#run method to execute it.
   #
   # For example, to copy all files from one directory to another:
-  #   filter("target/classes"=>"src/files")
+  #   filter("src/files").into("target/classes").run
   # To include only the text files, and replace each instance of <tt>${build}</tt> with the current
   # date/time:
-  #   filter("target/classes"=>"src/files").include("*.txt").using("build"=>Time.now)
