+=========================
+Removal of broken objects
+=========================
+
+The admin-UI now supports detection and deletion of broken objects. It
+is still limited to IApplication objects in the root folder. Options
+to repair broken objects are also still missing.
+
+We first setup the environment:
+
+ >>> import grok
+ >>> grok.grok(__name__)
+ >>> from zope.testbrowser.testing import Browser
+ >>> browser = Browser()
+ >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw')
+ >>> root = getRootFolder()
+
+Now we install an instance of ``GrokAdmin`` named `admin`::
+
+ >>> from grokadmin.app import GrokAdmin
+ >>> root['admin'] = GrokAdmin()
+ >>> list(root.keys())
+ [u'admin']
+
+If no broken applications are in the root, everything should look as
+usual:
+
+ >>> browser.open('http://localhost/admin/applications')
+ >>> 'Broken applications:' not in browser.contents
+ True
+
+Now we grok this module, to have a new application type available,
+which is intentionally broken:
+
+ >>> browser.open('http://localhost/admin/applications')
+ >>> 'PseudoBroken' in browser.contents
+ True
+
+We add an instance of that new type:
+
+ >>> subform = browser.getForm(name='PseudoBroken')
+ >>> subform
+ <zope.testbrowser.browser.Form object at 0x...>
+
+ >>> subform.getControl('Name your new app').value = 'mybrokenobj'
+ >>> subform.getControl('Create').click()
+
+and the broken object should show up in the applications list:
+
+ >>> print browser.contents
+ <html xmlns="http://www.w3.org/1999/xhtml">
+ ...
+ ...Broken applications:...
+ ...
+ ...(broken type: ...brokenobjs.PseudoBroken)...
+ ...This application is broken!...
+ ...
+
+If we want to delete the broken object, we can do so:
+
+ >>> ctrl = browser.getControl(name='items')
+ >>> ctrl.getControl(value='mybrokenobj').selected = True
+ >>> browser.getControl('Delete Selected').click()
+ >>> print browser.contents
+ <html xmlns="http://www.w3.org/1999/xhtml">
+ ...
+ ...Application `mybrokenobj` was successfully deleted.
+ ...
+
+and the 'Broken applications' section won't show up anymore:
+
+ >>> 'Broken applications:' not in browser.contents
+ True
+
+
+"""
+import grok
+from ZODB.broken import Broken
+class PseudoBroken(grok.Application, grok.Container, Broken):
+ """A class intentionally broken.
