-- TODO: When adding oConfigFile back, make oTaskDB a Maybe FilePath.
-- This way, it won't always overwrite the task db set in the config.
-- TODO: Add a [-c|--export-default-config CONFIGFILE] option
-- TODO: Add a [--initialize] flag to create a ~/.taskmachine/ folder and fill it with a default config and theme.
-- TODO: Have a look at other programs to see how they deal with this issue.
