      <para>
        The <application>OpenJPEG 2</application> source tarball shown above
        downloads with the correct name, openjpeg-&openjpeg2-version;.tar.gz,
        if using a browser such as Firefox. If you prefer to use a command
        line program such as wget, you normally would obtain
        v&openjpeg2-version;.tar.gz. To obtain this package with the proper
        filename, run:

<screen><userinput>wget -c &openjpeg2-download-http; \
