	. WARNING . WARNING . WARNING . WARNING . WARNING . WARNING .

	  We won't sanitize the CIB and the peinputs files, because
	  that would make them useless when trying to reproduce the
	  PE behaviour. You may still choose to obliterate sensitive
	  information if you use the -s and -p options, but in that
	  case the support may be lacking as well. The logs and the
	  crm_mon, ccm_tool, and crm_verify output are *not* sanitized.

	  Additional system logs (/var/log/messages) are collected in
	  order to have a more complete report. If you don't want that
	  specify -M.

	  IT IS YOUR RESPONSIBILITY TO PROTECT THE DATA FROM EXPOSURE!
