Bootstrap pipx

[ThatXliner]

How would this feature be useful?

Since pipx has dependancies, I would like a way to bootstrap pipx. I acknowledge that you can do pipx install pipx

Describe the solution you'd like
An alternative bootstrapping shell script.

Describe alternatives you've considered
A PyPi package for pipx installing pipx-install. Although it's more cross platform, it would take more work, in my opinion.
