usage: h5clear [OPTIONS] file_name
  OPTIONS
   -h, --help                Print a usage message and exit
   -V, --version             Print version number and exit
   -s, --status              Clear the status_flags field in the file's superblock
   -m, --image               Remove the metadata cache image from the file
   --filesize                Print the file's EOA and EOF
   --increment=C             Set the file's EOA to the maximum of (EOA, EOF) + C for
                             the file <file_name>.
                             C is >= 0; C is optional and will default to 1M when not set.
                             This option helps to repair a crashed file where the stored EOA
                             in the superblock is different from the actual EOF.
                             The file’s EOA and EOF will be the same after applying
                             this option to the file.

Examples of use:

h5clear -s file_name
  Clear the status_flags field in the superblock of the HDF5 file <file_name>.

h5clear -m file_name
  Remove the metadata cache image from the HDF5 file <file_name>.

h5clear --increment file_name
  Set the EOA to the maximum of (EOA, EOF) + 1M for the file <file_name>.

h5clear --increment=512 file_name
  Set the EOA to the maximum of (EOA, EOF) + 512 for the file <file_name>.
