File

./nofollowlist.module, line 55
Provides a nofollowlist filter.

Code

function nofollowlist_theme_registry_alter(&$theme_registry) {

  /**
   * Preliminary benchmarks indicate that invoking theme() can slow down the l() function
   * by 20% or more, and that some of the link-heavy Drupal pages spend more
   * than 10% of the total page request time in the l() function.
   *
   * So if 'nofollowlist_everywhere' is disabled
   * - delete 'nofollowlist_preprocess_link' from registry
