* [prompt-toolkit][6] : For topydo's _prompt_ mode, which offers a shell-like
interface with auto-completion.
* [arrow][8] : Used to turn dates into a human readable version.
* [backports.shutil_get_terminal_size][9] : Used to determine your terminal
window size. This function was
added to the standard library in
Python 3.3 and so is only
required in older versions of
Python.
