Well, I used it rarely, relying on the "import-wizard-for-dummy".
But I like the "api" that is used in both MEEP and MPB and that rely on 
h5utils: http://ab-initio.mit.edu/wiki/index.php/H5utils
They also provide "h5read.oct" to import their h5 in Octave. It could be 
interesting to use the same kind of syntax for Scilab...
