function drupal_install_system

Install the base system and any required database drivers.

Separated from the installation of other modules so core system functions can be made available while other modules are installed.

Parameters

array $install_state: An array of information about the current installation state. This is used to set the default language.

File

core/includes/install.inc, line 190
