To install the LP, run the shell script generated during the compilation: install_<LPname>.sh. The script must be run with power user privileges.
For example, to install the Australian LP, execute the following command:
# sudo ./install_en_AU.sh
The LP is now installed. To make sure of this, log in to the Plesk Sitebuilder Administrator Panel, go to Server > Languages and find the name of your LP in the list of available languages.
