HDF5 - C runtime files - MPICH2 version (transitional package)

 Hierarchical Data Format 5 (HDF5) is a file format and library for
 storing scientific data. HDF5 was designed and implemented to address
 the deficiencies of HDF4.x. It has a more powerful and flexible data
 model, supports files larger than 2 GB, and supports parallel I/O.
 .
 This package contains the C runtime files for use with MPICH2.
 .
 This transitional package helps upgrading from the single package bundling
 multiple libraries in buster to the individiual library packages in
 bullseye. It can be safely removed.
