vpsready-0.1.0-alpha.4 is not a library.
vpsready
The vps-ready command, installed under the name vpsready.
This crate contains no code of its own: it runs vps_ready::cli::main() and is published from the same repository and release workflow as vps-ready, so the name cannot be taken by an unrelated crate.
Until v0.1.0 only pre-releases exist, and cargo install skips them by default: add --version 0.1.0-alpha.4 (or the latest alpha).
See the vps-ready README for documentation.
