).
.TP
-.B --rsyncable
-While compressing, synchronize the output occasionally based on the input.
-This increases size by less than 1 percent most cases, but means that the
-.BR rsync (1)
-program can much more efficiently synchronize files compressed with this flag.
-.I gunzip
-cannot tell the difference between a compressed file created with this option,
-and one created without it.
-.TP
.B \-S .suf --suffix .suf
Use suffix .suf instead of .gz. Any suffix can be given, but suffixes
other than .z and .gz should be avoided to avoid confusion when files
Previous versions of gzip used
the .z suffix. This was changed to avoid a conflict with
-.IR pack "(1)".
+.I pack.
.TP
.B \-t --test
Test. Check the compressed file integrity.
On Vax/VMS, the name of the environment variable is GZIP_OPT, to
avoid a conflict with the symbol set for invocation of the program.
