AT_SETUP([sparse files in MV archives])

# Check if sparse files are correctly split between GNU multi-volume
# archives.
# There are two cases: the file can be split within an empty (null) block,
# or within a data block. Since null blocks are not archived, the first
# case means the file is split between two consecutive data blocks.
