title: Complete django DB reset
body: <p>How do I completely reset my Django (1.2 alpha) DB (dropping all tables, rather than just clearing them)?</p>
  
  <p><code>manage.py flush</code> does too little (won't work if there are schema changes) and <code>manage.py reset</code> requires me to specify all apps (and appears to take a format that is different from just " ".join(INSTALLED_APPS)). I can obviously achieve this in a DB specific way, but I figured there must be a sane, DB backend agnostic way to do this.</p>
  
  <p>[Edit: I'm looking for something that I can call from a script, e.g. a Makefile and that continues to work if I change the backend DB or add to <code>settings.INSTALLED_APPS</code>]</p>
