"""
Install a package or packages, and run any associated installers.
## Args
mix igniter.install package1 package2 package3
## Package formats
* `package` - The latest version of the package will be installed, pinned at the
major version, or minor version if there is no major version yet.
* `package@version` - The package will be installed at the specified version.
If the version given is generic, like `3.0`, it will be pinned as described above.
if it is specific, like `3.0.1`, it will be pinned at that *exact* version with `==`.
* `package@git:git_url` - The package will be installed from the specified git url.
* `package@github:project/repo` - The package will be installed from the specified github repo.
* `package@path:path/to/dep` - The package will be installed from the specified path.
Additionally, a Git ref can be specified when using `git` or `github`:
* `package@git:git_url@ref`
## Switches
* `--dry-run` - Run the task without making any changes.
* `--yes` - Automatically answer yes to any prompts.
* `--yes-to-deps` - Automatically answer yes to any prompts about installing new deps.
* `--example` - Request that installed packages include initial example code.
