Michel is your friendly mate that helps you managing your todo list. It can push/pull flat text files to google tasks.
Michel has only two commands:
which prints the default todo list on the standard output
michel push < TODO.txt >
which replaces the default todo list with the content of TODO.txt
Michel aims at being simple: it does not handle due dates nor notes.
One line is one task. Indented lines are subtasks of the "parent" line.
