It's now easier to test out a new framework, 
package manager, or other build tool without disrupting the rest of your
 project. We've added support for configuration overrides on a per-deployment 
basis powered by six new properties for `vercel.json`.

The six supported settings are:

- `framework`
- `buildCommand`
- `outputDirectory`
- `installCommand`
- `devCommand`
- `ignoreCommand`
