Comment (by barry.wardell):

 Replying to [comment:3 rhaas]:
 > I am not sure if Ian's Mathematica based postprocessing system parses
 parfiles or not. If it does it may benefit from being able to parse the
 better formatted "/Parameters and Global Attributes/All Parameters"
 dataset instead (since it already has all substitutions performed,
 comments removed, special characters escaped).

 SimulationTools currently parses the parameter file to infer a lot of
 required information about a simulation. It doesn't look at the
 "/Parameters and Global Attributes/All Parameters" dataset at all. It
 would certainly be nice to have a more robust system, where all metadata
 related to a simulation is stored in a standard and easily parseable way
 (such a system was proposed in #1370 - there is a distinction between
 metadata and parameters, but I assume it is the former that Roland would
 really like).

 I am not convinced that storing parameters as a dataset in each HDF5 file
 is the right way to go.  Would it not be better to have a single place
 where all simulation metadata is stored?
