HDF5 BitRound filter plugin -- provenance and license
======================================================

This plugin adapts two BSD-style sources, both authored by Charlie Zender:

  * the BitRound quantization core, from netcdf-c (libsrc4/nc4var.c,
    NC_QUANTIZE_BITROUND; PR #2232). The netcdf-c repository is copyright
    UCAR (University Corporation for Atmospheric Research).

  * the HDF5 filter-plugin scaffolding (cd_values layout, set_local /
    can_apply pattern), from the BitGroom plugin in the ccr project,
    copyright (c) Charlie Zender / ccr.
