cms detect links spelling and code mistakes

Not sure if this is the correct forum to post this question, but does anyone know if a w开发者_如何学JAVAebsite cms system exists which automatically detects and reports spelling mistakes, broken links, coding errors etc etc.

When I say cms, I mean something like joomla, drupal etc.

If they don't have those capabilities built in, is it possible to get a cms system and find addons which add those capabilities?

You already tagged the question 'drupal', so I feel I can point you toward Drupal's spelling checker module and link checker module.

But I suspect other CMS systems also have perfectly good modules for similar functionality.
