    """ Since v1.1
        Seismic Unix style aliases for binary and trace header fields.

    About names:
        Seismic Unix does not have names for all possible fields, as it came
        around during an early revision of SEG-Y, and names for these fields
        are created by segyio in their absence. If Seismic Unix starts
        providing names for these fields, they will be added to these alies,
        and in conflicts take presedence after some time. If there are no
        conflicts, segyio names are considered for deprecation on a
        case-by-case basis, but will most likely be supported along with the
        Seismic Unix name.
