function update_module_enable(array $modules) {
  foreach ($modules as $module) {
    // Check for initial schema and install it. The schema version of a newly
    // installed module is always 0. Using 1000 here would be inconsistent
    // since $module_update_1000() may involve a schema change, and we want
    // to install the schema as it was before any updates were added.

    // updates since the module's inception are executed in a core upgrade.
