parse error in civicrm_handler_relationship_relationship.inc since upgrade to 4.6.11
I just hit this error, too. It's in 4.6.11 and 4.6.12. It appears to be fixed in 4.7.1.

Line 56 in the file is the culprit. It should be

'#description' =&gt; t('Choose to limit this relationship to one or more specific types of CiviCRM relationship.'),


Here's the commit that fixes it.
