"""This script converts a supported data file (SPEC, EDF,...) to a HDF5 file.
By default, it creates a new output file or fails if the output file given
on the command line already exist, but the user can choose to overwrite
existing files, or append SPEC data to existing HDF5 files.
In case of appending data to HDF5 files, the user can choose between ignoring
input data if a corresponding dataset already exists in the output file, or
overwriting existing datasets.
By default, new scans are written to the root (/) of the HDF5 file, but it is
possible to specify a different target path.
