bower install jquery.localScroll
Requires jQuery.ScrollTo (http://github.com/flesler/jquery.scrollTo)
The hash of settings is passed in to jQuery.ScrollTo, so, in addition to jQuery.LocalScroll's settings, you can use any of jQuery.ScrollTo's. Check that plugin's documentation for further information.
If you want to convert the links from ALL over the page, with the same settings, just call $.localScroll(...) instead of $(...).localScroll(...)
Most of this plugin's defaults, belong to jQuery.ScrollTo, check it's demo for an example of each option.
