description:
- The local directory from where to install
notest:
description:
- Do not run unit tests
type: bool
default: 'no'
locallib:
description:
- Specify the install base to install modules
type: bool
default: 'no'
mirror:
description:
- Specifies the base URL for the CPAN mirror to use
type: bool
