How to get the orig.tar.gz used:

Since upstream doesn't ship tarballs, I've added a "get-orig-source" target
in debian/rules to allow easy creation of the tarball I used. Basically it
downloads the source from the svn repository, but excludes all files which
are not suitable for Debian:

Autogenerated files:

elycharts.js (Generated by combining individual source files)
elycharts.min.js (Generated with yuicompressor)
index.html (These are a result of using wget to access the repository)

Files with unclear copyright:

docs/demo*.html (These don't have a copyright header, I've mailed upstream
                 and asked them to clarify the license)

Convenience copies of JS libraries which are available in Debian:

libs/jquery.js (Available as libjs-jquery)
libs/raphael.js (Availabel as libjs-raphael)
