Plugman is a utility for validating, installing, and publishing your custom build plugin for Cordova. Plugman can be installed via the NPM command:
$ npm install -g plugman
You need to test and validate your plugin in your project before you can publish it. Using plugman install you can install the plugin for a specific platform, as mentioned previously:
$ plugman install --platform android --project /path/to/project/www --plugin /path/to/custom-plugin
We will not go deep into plugman, but you can perform functions such as installing, uninstalling, search registry, and getting information via plugman.
