%global _description %{expand:
HighFive is a modern header-only C++11 friendly interface for libhdf5.

HighFive supports STL vector/string, Boost::UBLAS, Boost::Multi-array and
Xtensor. It handles C++ from/to HDF5 with automatic type mapping. HighFive does
not require additional libraries (see dependencies).

It integrates nicely with other CMake projects by defining (and exporting) a
HighFive target.

Design:
- Simple C++-ish minimalist interface
- No other dependency than libhdf5
- Zero overhead
- Support C++11

Feature support:
- create/read/write files, datasets, attributes, groups, dataspaces.
- automatic memory management / ref counting
- automatic conversion of std::vector and nested std::vector from/to any
  dataset with basic types
- automatic conversion of std::string to/from variable length string dataset
- selection() / slice support
- parallel Read/Write operations from several nodes with Parallel HDF5
- Advanced types: Compound, Enum, Arrays of Fixed-length strings, References
  etc… (see ChangeLog)

Known flaws:
- HighFive is not thread-safe. At best it has the same limitations as the HDF5
  library. However, HighFive objects modify their members without protecting
  these writes. Users have reported that HighFive is not thread-safe even when
  using the threadsafe HDF5 library, e.g.,
  https://github.com/BlueBrain/HighFive/discussions/675.
- Eigen support in core HighFive is broken. See
  https://github.com/BlueBrain/HighFive/issues/532. H5Easy is not affected.
- The support of fixed length strings isn’t ideal.}
