-// link follower for uzbl
-// requires http://github.com/DuClare/uzbl/commit/6c11777067bdb8aac09bba78d54caea04f85e059
-//
-// first, it needs to be loaded before every time it is used.
-// One way would be to use the load_commit_handler:
-// set load_commit_handler = sh 'echo "script /usr/share/uzbl/examples/data/scripts/linkfollow.js" > "$4"'
-//
-// when script is loaded, it can be invoked with
-// bind f* = js hints.set("%s", hints.open)
-// bind f_ = js hints.follow("%s",hints.open)
-//
-// At the moment, it may be useful to have way of forcing uzbl to load the script
-// bind :lf = script /usr/share/uzbl/examples/data/scripts/linkfollow.js
-//
-// The default style for the hints are pretty ugly, so it is recommended to add the following
-// to config file
-// set stylesheet_uri = /usr/share/uzbl/examples/data/style.css
-//
-// based on follow_Numbers.js
-//
-// TODO: fix styling for the first element
-// TODO: emulate mouseover events when visiting some elements
-// TODO: rewrite the element->action handling
