19# Description: When creating POSIX multivolume archives, tar may in
20# some cases write an extended header at the end of one volume, and
21# the corresponding ustar header at the beginning of the next volume.
22# Such archives do not fully comply with the POSIX specs, but tar must
23# be able to read them anyway. This is what this script tests.

25# See function try_new_volume, in file src/buffer.c near line 1227
26# for additional details.
