# The TAR component will produce a  GNU tar 1.13.x format
# archive by default.
# It is also possible to create PAX -- POSIX 1003.1-2001 format
# or USTAR -- POSIX 1003.1-1988 format.
# Set the WriteFormat property to "gnu", "pax", or "ustar" to
# choose the output TAR format:
CkTar_put_WriteFormat $tar "gnu"

# Add a directory tree to be included in the output TAR archive:

# Note: You may use UNC paths, absolute, or relative paths.
