It offers read/write access to hdf5 archives through a hierarchical interface.
I am adding it, because pandas depends on tables for hdf5 read/write
functionality.
Note: The name is a bit of an issue. The project is called pytables, whereas
the python module is simply called tables. I chose to name the nix-expression
tables for consistency with the source-tarball and the module name.
