This script enables markup of the form <<|TrailPage|>> to be
used to build "trails" through wiki documents.
This feature is automatically included from stdconfig.php unless
disabled by $EnableWikiTrails = 0; . To explicitly include this feature,
execute
include_once("scripts/trails.php");
from config.php somewhere.
Once enabled, the <<|TrailPage|>> markup is replaced with
<< PrevPage | TrailPage | NextPage >> on output. TrailPage should
contain either a bullet or number list defining the sequence of pages
in the "trail".
The ^|TrailPage|^ markup uses the depth of the bullets to display
the ancestry of the TrailPage to the current one. The <|TrailPage|>
markup is like <<|TrailPage|>> except that "< PrevPage |" and
"| NextPage >" are omitted if at the beginning or end of the
trail respectively. Thanks to John Rankin for contributing these
markups and the original suggestion for WikiTrails.
