Is there a way to install packages "globally" using dub?
For example, when using the node package manager (NPM) you can install a package "globally" (so it is available for the current user from the command line) using the `--global` flag as follows:
`npm install --global typescript`This would make `tsc` command (which invokes the TypeScript compiler) available from the command line outside of any project. This would be convenient for packages like dfmt.
