     the manual page with: `docbook-to-man manpage.sgml | nroff -man |

        debian/rules file targets (such as build), you will need to include
        docbook-to-man in your Build-Depends control field.

    <title>DESCRIPTION</title>

    <para>This manual page documents briefly the <command>&dhpackage;</command> command.</para>

    <para><command>&dhpackage;</command> attempts to tap the beat and detect
    beat locations in musical sounds. When started with an input file argument
    (<option>-i</option>), aubiotrack print the beat locations in second
    detected in the file. Without an input file is given, aubiotrack will start
    as a jack client and play a woodblock sound at predicted beat
    locations.</para>
