cordova hook script to copy icons and splash screens to platform directories

I've updated the Gist to support Cordova 3.4

https://gist.github.com/Cyril-sf/11409317/revisions

hooks/README.md says:

Any scripts you add to these directories will be executed before
and after the commands corresponding to the directory name.

Hook Directories

The following subdirectories will be used for hooks:

after_build/
after_compile/
after_docs/
after_emulate/
after_platform_add/
after_platform_rm/
after_platform_ls/
after_plugin_add/
after_plugin_ls/
after_plugin_rm/
after_plugin_search/
after_prepare/
after_run/
after_serve/
before_build/
before_compile/
before_docs/
before_emulate/
before_platform_add/
before_platform_rm/
before_platform_ls/
before_plugin_add/
before_plugin_ls/
before_plugin_rm/
before_plugin_search/
before_prepare/
before_run/
before_serve/

So which one should this script go into? I'm not seeing anything happen with it in the root hooks directory. I'm guessing it should go in after_build where I'm seeing it run.

This doesn't seem to work anymore. I also get the error Error: Cannot find module 'cordova/src/util'. Does anyone know how to fix this problem? I'm using Cordova 3.6.3-0.2.13

I have fixed the error for cordova 3.6.3. You have to:

npm install cordova-lib

And replace lines from 3 to 6 with:

var cordova_util = require('cordova-lib/src/cordova/util');
var projectRoot = cordova_util.isCordova(process.cwd());
var projectXml = cordova_util.projectConfig(projectRoot);
var ConfigParser = require('cordova-lib/src/ConfigParser/ConfigParser');
var projectConfig = new ConfigParser(projectXml);

or simply use my fixed version: https://gist.github.com/brugnara/a6cbd8ba90a3a73aa91a
