use
caution
This command has been deprecated and its functionality was merged into proto install
in v0.39. Use that command instead!
The proto use (or proto u) command will download and install all tools and plugins from all
parent .prototools configuration files, and any versions detected in
the current working directory (if not defined in .prototools).
$ proto use
This command does not install tools for versions pinned in the global
~/.proto/.prototoolsfile.
