+xxhsum(1) -- print or check xxHash non-cryptographic checksums
+==============================================================
+
+SYNOPSIS
+--------
+
+`xxhsum` [<OPTION>] ... [<FILE>] ...<br/>
+`xxhsum -b` [<OPTION>] ...
+
+DESCRIPTION
+-----------
+
+Print or check xxHash (32 or 64bit) checksums.  When <FILE> is `-`, read
+standard input.
+
+`xxhsum` supports a command line syntax similar but not indentical to
+md5sum(1).  Differences are: `xxhsum` doesn't have text/binary mode switch
+(`-b`, `-t`);  `xxhsum` always treats file as binary file;  `xxhsum` has hash
+bit width switch (`-H`);
+
+Since xxHash is non-cryptographic checksum algorithm, `xxhsum` should not be
+used any more for security related purposes.
+
+`xxhsum -b` invokes benchmark mode. See [OPTIONS](#OPTIONS) and [EXAMPLES](#EXAMPLES) for details.
+
+OPTIONS
+-------
+
+* `-c`, `--check`:
+  Read xxHash sums from the <FILE>s and check them
+
+* `-h`, `--help`:
+  Display help and exit
+
+* `-H`<HASHTYPE>:
+  Hash selection.  <HASHTYPE> means `0`=32bits, `1`=64bits.
+  Default value is `1` (64bits)
+
+* `--little-endian`:
+  Set output hexadecimal checksum value as little endian convention.
+  By default, value is displayed as big endian
+
+* `-V`, `--version`:
+  Display xxhsum version
+
+**The following four options are useful only when verifying checksums (`-c`)**
+
+* `--quiet`:
+  Exit non-zero for improperly formatted checksum lines
+
+* `--strict`:
+  Don't print OK for each successfully verified file
+
+* `--status`:
+  Don't output anything, status code shows success
+
+* `-w`, `--warn`:
+  Warn about improperly formatted checksum lines
+
+**The following options are useful only benchmark purpose**
+
+* `-b`:
+  Benchmark mode.  See [EXAMPLES](#EXAMPLES) for details.
+
+* `-B`<BLOCKSIZE>:
+  Only useful for benchmark mode (`-b`). See [EXAMPLES](#EXAMPLES) for details.
+  <BLOCKSIZE> specifies benchmark mode's test data block size in bytes.
+  Default value is 102400
+
+* `-i`<ITERATIONS>:
+  Only useful for benchmark mode (`-b`). See [EXAMPLES](#EXAMPLES) for details.
+  <ITERATIONS> specifies number of iterations in benchmark. Single iteration
+  takes at least 2500 milliseconds. Default value is 3
+
+EXIT STATUS
+-----------
+
+`xxhsum` exit `0` on success, `1` if at least one file couldn't be read or
+doesn't have the same checksum as the `-c` option.
+
+EXAMPLES
+--------
+
+Output xxHash (64bit) checksum values of specific files to standard output
+
+    $ xxhsum -H1 foo bar baz
+
+Output xxHash (32bit and 64bit) checksum values of specific files to standard
+output, and redirect it to `xyz.xxh32` and `qux.xxh64`
+
+    $ xxhsum -H0 foo bar baz > xyz.xxh32
+    $ xxhsum -H1 foo bar baz > qux.xxh64
+
+Read xxHash sums from specific files and check them
+
+    $ xxhsum -c xyz.xxh32 qux.xxh64
+
+Benchmark xxHash algorithm for 16384 bytes data in 10 times. `xxhsum`
+benchmarks xxHash algorithm for 32-bit and 64-bit and output results to
+standard output.  First column means algorithm, second column is source data
+size in bytes, last column means hash generation speed in mega-bytes per
+seconds.
+
+    $ xxhsum -b -i10 -B16384
