+See the [documentation] for details.
 
-      This tool concatenates MP3 files without re-encoding. It can join constant
-      bit-rate (CBR) files, variable bit-rate (VBR) files, or a mixture of both.
-
-      If a set of input CBR files share the same bit-rate, the output file will
-      also be CBR; if the input files have different bit-rates, the output file
-      will be VBR.
-
-      Files to be merged can be specified as a list of filenames:
-
-        $ mp3cat one.mp3 two.mp3 three.mp3
-
-      Alternatively, an entire directory of .mp3 files can be merged:
-
-        $ mp3cat --dir /path/to/directory
-
-    Arguments:
-      [files]                 List of files to merge.
-
-    Options:
-      -d, --dir <path>        Directory of files to merge.
-      -i, --interlace <path>  Interlace a spacer file between each input file.
-      -o, --out <path>        Output filename. Defaults to 'output.mp3'.
-
-    Flags:
-      -f, --force             Overwrite an existing output file.
-      -h, --help              Display this help text and exit.
-      -q, --quiet             Run in quiet mode.
-      -t, --tag               Copy the ID3 tag from the first input file.
-      -v, --version           Display the application's version number and exit.
