etmtk is an acronym for event and task manager.

In contrast to most calendar/todo applications, creating items (events, tasks,
and so forth) in etm does not require filling out fields in a form. Instead,
items are created as free-form text entries using a simple, intuitive format
and stored in plain text files.

Before running etm for the first time run this command as user:
mkdir ~/.etm
