* Download Magento by a list of git repos and zip files (mageplus, magelte, official community packages).
* Try to create database if it does not exist.
* Installs Magento sample data if available (since version 1.2.0).
* Starts Magento installer
* Sets rewrite base in .htaccess file

Example of an unattended Magento CE 1.7.0.2 installation:

   $ n98-magerun.phar install --dbHost="localhost" --dbUser="mydbuser" --dbPass="mysecret" --dbName="magentodb" --installSampleData=yes --useDefaultConfigParams=yes --magentoVersionByName="magento-ce-1.7.0.2" --installationFolder="magento" --baseUrl="http://magento.localdomain/"

Additionally, with --noDownload option you can install Magento working copy already stored in --installationFolder on
the given database.
