	/*! 
	@brief Install a Godot package from the Asset Library in the current project.
	By default, packages are stored in a global directory and linked to the project
	where the tool is executed. Use the `--jobs` option to install packages in 
	parallel. Specify which remote source to use by passing the `--remote` option.
	By default, the first remote source will by used. Alternatively, if the
	`--use-remote=false` option is passed, then the tool will only attempt to fetch the
	package from cache. Use the `--use-cache=false` option to fetch package only from 
	remote source.

	`gdpm install "super cool example package"
		
	To only install a package global without linking to the project, use the 
	`--global-only` option.

	`gdpm install --global-only "super cool example package"

	To install a package to a local project only, use the `--local-only` option. 
	This will extract the package contents to the project location instead of the
	global install location. Use the `--path` option to specify an alternative
	path.

	`gdpm install --local-only "super cool example package" --path addons/example

	To copy the package to a project instead of linking, use the `--clone` option.

	`gdpm install --clone "super cool example package"
