I have installed alr

PS C:\path\to\Rejuvenation-Ada\workshop\tests> alr version

When I call alr as follows alr help toolchain

I get

SUMMARY
   Manage Alire-provided toolchains

USAGE
   alr toolchain [options] [-u|--uninstall] [-i|--install crate[version set]] | --select [--local] [releases] [--disable-assistant]

...

However, both the install and uninstall flags should be passed a crate with optional version set. So I had expected something like alr toolchain [options] [-u|--uninstall|-i|--install crate[version set]] | --select [--local] [releases] [--disable-assistant] or alr toolchain [options] [-u|--uninstall crate[version set]] | [-i|--install crate[version set]] | --select [--local] [releases] [--disable-assistant]

Good catch, thanks for the report.

I still wonder if we should keep the toolchain install/uninstall feature in. It's a convenient way to install the toolchains built for the Alire project, but it doesn't fit in the Alire workflow, and would be better replaced by a GitHub action...
