When multiple charts are specified, Helm will attempt to install all of them,
following the resolution process described above.
As a special case, if the flag --chart-path is specified, Helm will look for a
Chart.yaml file and manifests/ directory at that path, and will install that
chart if found. In this case, you may not specify multiple charts at once.
