  ## `pnpm.installPkgs(pkgsToInstall, [options])`
  
  Install packages.
  
  **Arguments:**
  
  * `pkgsToInstall` - *Object | String[]* - either an object that maps package names to version ranges or inputs usually passed to `npm install` (e.g., `foo@1.0.0`, `foo`).
  * `options.save` - *Boolean* - package will appear in `dependencies`.
  * `options.saveDev` - *Boolean* - package will appear in `devDependencies`.
  * `options.saveOptional` - *Boolean* - package will appear in `optionalDependencies`.
  * `options.saveExact` - *Boolean* - saved dependencies will be configured with an exact version rather than using npm's default semver range operator.
  * `options.global` - *Boolean* - the packages will be installed globally rather than locally.
  * `options.cwd` - *String* - the directory in which the installation will be performed. By default the `process.cwd()` value is used.
  * `options.quiet` - *Boolean* - `false` by default. No output to the console.
  
  **Returns:** a Promise
  
  **Example:**
  
  ```js
  const pnpm = require('pnpm')
  
  pnpm.install({
    'is-positive': '1.0.0',
    'hello-world': '^2.3.1'
  }, { save: true, quiet: true })
  ```
  
  ## `pnpm.install([options])`
  
  Install all modules listed as dependencies in `package.json`.
  
  **Arguments:** (same as in named install and additionally)
  
  * `options.production` - *Boolean* - `false` by default or `true` when the `NODE_ENV` environment variable is set to `production`. Modules listed in `devDependencies` will not be installed.
  
  ## `pnpm.uninstall(pkgsToUninstall, [options])`
  
  Uninstalls a package, completely removing everything pnpm installed on its behalf.
  
  **Arguments:**
  
  * `pkgsToUninstall` - *String[]* - the package names to be uninstalled.
  * `options.save` - *Boolean* - the package will be removed from `dependencies`.
  * `options.saveDev` - *Boolean* - the package will be removed from `devDependencies`.
  * `options.saveOptional` - *Boolean* - the package will be removed from `optionalDependencies`.
  * `options.global` - *Boolean* - the packages will be uninstalled globally.
  
  ## `pnpm.linkFromRelative(lintTo, [options])`
  
  Create a symbolic link from the linked package to the current working directory's `node_modules` (and to the `node_modules/.bin`).
  
  **Arguments:**
  
  * `options.cwd` - *String* - by default `process.cwd()`.
  
  ## `pnpm.linkToGlobal([options])`
  
  Create a symbolic link from the package in the current working directory to the global `node_modules`.
  
  **Arguments:**
  
  * `options.cwd` - *String* - by default `process.cwd()`.
  
  ## `pnpm.linkFromGlobal(pkgName, [options])`
  
  Create a symbolic link to the specified package from the global `node_modules` to the current working directory's `node_modules`.
  
  **Arguments:**
  
  * `options.cwd` - *String* - by default `process.cwd()`.
  
  ## `pnpm.prune([options])`
  
  Remove extraneous packages. Extraneous packages are packages that are not listed on the parent package's dependencies list.
  
  **Arguments:**
  
  * `options.production` - *Boolean* - by default `false`. If this property is `true`, prune will remove the packages specified in `devDependencies`.
  * `options.cwd` - *String* - by default `process.cwd()`.
  
  ## `pnpm.prunePkgs(pkgs, [options])`
  
  Remove extraneous packages specified in the `pkgs` arguments. Extraneous packages are packages that are not listed on the parent package's dependencies list.
  
  **Arguments:**
  
  * `pkgs` - *String[]* - prune only the specified packages.
  * `options.production` - *Boolean* - by default `false`. If this property is `true`, prune will remove the packages specified in `devDependencies`.
  * `options.cwd` - *String* - by default `process.cwd()`.
