 more files.
 
 It supports three CRC algorithms (selected via `--mode=<alg>`):
-* `crc64-ecma` (*default*) uses the [ECMA polynomial](https://godoc.org/hash/crc64#pkg-constants) to compute a 64-bit CRC.
+* `crc64-ecma` uses the [ECMA polynomial](https://godoc.org/hash/crc64#pkg-constants) to compute a 64-bit CRC.
 * `crc64-iso` uses the [ISO polynomial](https://godoc.org/hash/crc64#pkg-constants) to compute a 64-bit CRC.
-* `crc32` uses the [IEEE polynomial](https://godoc.org/hash/crc32#pkg-constants) to compute a 32-bit CRC.  This is equivalent to the `crc32` linux binary.

 If only a single file is specified on the command line, then only the hexadecimal hash is printed.  If more than one file is specified, the output will be
