<p>To build a breadcrumb trail, Crumbs takes the system path of the current
page, and determines a "parent path". This process is repeated with the parent,
until it arrives at the front page path, or until a loop is detected.</p>
<p>There are plenty of criteria available, that Crumbs can use to find a parent
path. This settings form allows to enable, disable and prioritize these
criteria.</p>
<p>Criteria further up in the "Enabled" section take precedence over those
further down. Criteria in the "Disabled" section have their effect nullified.
Criteria in the "Inherit / automatic" section inherit the status from
the parent wildcard criterion, unless they are "disabled by default".</p>
