# HDF5 depends on zlib and provides a C interface by default.
# Optionally, it can be built with szip (which has limitations on
# commercial use and thus is non-free), MPI, and C++ and Fortran bindings.
# C++ and Fortran bindings may not be thread-safe:
# building either and passing --enable-threadsafe is unsupported.
# Additionally, the 'high-level' bindings are incompatible with threadsafe
# builds, due to inadequate locking.
