Download...
There are various sizes and types of downloads available, so you can decide on ease of use versus time to load, take you pick and enjoy.
Compressed...
Compressed using YUI compressor - no comments or whitespace and partially munged, but preserved semicolons for extra safety.
Fully documented...
Includes all comments and documentation for easy reference.
To use, simply save it as a .js file, add it in a script tag to the head of your document, and wire up some validation.
Svn repository...
Alternatively, you can get the 1.3 source straight from the svn repository, which will get you all the other goodies, like the unit tests. Check it out via svn from:
svn://livevalidation.com/livevalidation/tags/1.3
