    <title>Command Explanations</title>

    <para><command>patch -Np1 -i ../fam-&fam-version;-dnotify-1.patch</command>:
    This patch enables <application>FAM</application> to use
    the Linux kernel dnotify mechanism to inform the calling process of
    file modifications, rather than polling the file system for
    modifications.</para>

    <para><command>chmod -v 755 configure</command>: <command>configure</command> is
    set to read-only and <command>autoreconf</command> will fail if the
    permissions aren't changed.</para>

    <para><command>autoreconf -f -i</command>: The autotools need rebuilding
    because the dnotify patch affects <filename>configure.ac</filename> and
    <filename>Makefile.am</filename>.</para>
