-Usage: humanfriendly [OPTIONS]
-
-Human friendly input/output (text formatting) on the command
-line based on the Python package with the same name.
-
-Supported options:
-
-  -c, --run-command
-
-    Execute an external command (given as the positional arguments) and render
-    a spinner and timer while the command is running. The exit status of the
-    command is propagated.
-
-  --format-table
-
-    Read tabular data from standard input (each line is a row and each
-    whitespace separated field is a column), format the data as a table and
-    print the resulting table to standard output. See also the --delimiter
-    option.
-
-  -d, --delimiter=VALUE
-
-    Change the delimiter used by --format-table to VALUE (a string). By default
-    all whitespace is treated as a delimiter.
-
-  -l, --format-length=LENGTH
-
-    Convert a length count (given as the integer or float LENGTH) into a human
-    readable string and print that string to standard output.
-
-  -n, --format-number=VALUE
-
-    Format a number (given as the integer or floating point number VALUE) with
-    thousands separators and two decimal places (if needed) and print the
-    formatted number to standard output.
-
-  -s, --format-size=BYTES
-
-    Convert a byte count (given as the integer BYTES) into a human readable
-    string and print that string to standard output.
-
-  -b, --binary
-
-    Change the output of -s, --format-size to use binary multiples of bytes
-    (base-2) instead of the default decimal multiples of bytes (base-10).
-
-  -t, --format-timespan=SECONDS
-
-    Convert a number of seconds (given as the floating point number SECONDS)
-    into a human readable timespan and print that string to standard output.
-
-  --parse-length=VALUE
-
-    Parse a human readable length (given as the string VALUE) and print the
-    number of metres to standard output.
-
-  --parse-size=VALUE
-
-    Parse a human readable data size (given as the string VALUE) and print the
-    number of bytes to standard output.
-
-  --demo
-
-    Demonstrate changing the style and color of the terminal font using ANSI
-    escape sequences.
-
-  -h, --help
-
-    Show this message and exit.
