    <title>Command Explanations</title>

    <para><command>sed -i '/copy_file_range(/s/copy/xfs_&amp;/'</command>:
    glibc-2.27 now defines copy_file, so rename the package function.</para>

    <para><command>make DEBUG=-DNDEBUG</command>: Turns off debugging
    symbols.</para>

    <para><parameter>INSTALL_USER=root INSTALL_GROUP=root</parameter>: This
    sets the owner and group of the installed files.</para>

    <para><parameter>LOCAL_CONFIGURE_OPTIONS="..."</parameter>: This passes
    extra configuration options to the <filename>configure</filename> script.
    The example <parameter>--enable-readline</parameter> parameter
    enables linking the XFS programs with the
    <filename class="libraryfile">libreadline.so</filename> library, in order
    to allow editing interactive commands.</para>

    <para><option>OPTIMIZER="..."</option>: Adding this parameter to
    the end of the <command>make</command> command overrides the
    default optimization settings.</para>
