For that reason, any usage of the CLI can be accomplished using a remote copy as seen in the below install command.
`Viv` is a standalone dependency-free `venv` creator (just needs python + pip).
`Viv` helps you ignore silly things like managing temporary or rarely used virtual environments,

`Viv`'s uncompromising insistence on portability means that it will always,
only use the standard library and never exceed a single script.
See the [documentation](https://viv.dayl.in/viv.py) or the [examples](https://github.com/daylinmorgan/viv/tree/main/examples) to get started.
