-The [Winston.jl](https://github.com/nolta/Winston.jl) and
-[PyPlot.jl](https://github.com/stevengj/PyPlot.jl) plotting packages are
-currently supported. See the ijulia notebooks:
-* [Winston](http://nbviewer.ipython.org/github/JuliaStats/KernelDensity.jl/blob/master/examples/Winston.ipynb)
-* [PyPlot](http://nbviewer.ipython.org/github/JuliaStats/KernelDensity.jl/blob/master/examples/PyPlot.ipynb)

-We plan to include support for other plotting packages: please file an issue
-if your favourite one is not yet available.
