Tip: if you save your task file in the todo folder that Todo.txt
Touch creates in your Dropbox folder, and you turn on automatic importing and
exporting of Todo.txt, %(name)s will keep the task file and the
todo.txt file in sync. Please note that another file, named after the .txt file
with '-meta' appended, is also generated. This is used internally by %(name)s
in order to keep track of what has been modified in the .txt file; don't modify
or delete it.
