<sect2>
<title>Command explanations</title>

<para><command>patch -Np1 -i ../fam-&fam-version;-dnotify-1.patch</command>: 
This patch enables <application><acronym>FAM</acronym></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>autoreconf -f -i</command>
This command is necessary since the dnotify patch affects 
<filename>configure.ac</filename> and <filename>Makefile.am</filename>.</para>
