path:
required: true
aliases: [ dest, destfile ]
description:
- Path to the file that contains the usernames and passwords
name:
required: true
aliases: [ username ]
description:
- User name to add or remove
password:
required: false
description:
- Password associated with user.

choices: [ present, absent ]
default: "present"
description:
- Whether the user entry should be present or not
create:
required: false

notes:
- "This module depends on the I(passlib) Python library, which needs to be installed on all target systems."
