How to extend?

[jarvist]

Is there a preferred method / approach to extending this package?
In particular, I would a HDF5 reader for VASP, but I don't really know whether it makes most sense to write a (HDF.jl depending) function in AtomsIO.jl; or write a vasp_HDF5.jl package elsewhere and wrap here, or ... ?

Great idea, thanks for getting in touch @jarvist.

To be honest I think both could make sense. I would say if it's just a few lines it might as well live here, since the code won't be of much other use anyway.

If you are worried about the HDF5 dependency ... we can always make it a package extension.
