137 the directives in <filename>Local/Makefile</filename> which is created from
138 the <filename>src/EDITME</filename> file. This command specifies the minimum
139 set of options. Descriptions for the options are listed below.</para>

149 <para><parameter>EXIM_USER=exim</parameter>: This tells
150 <application>Exim</application> that after the daemon no longer needs
151 <systemitem class="username">root</systemitem> privileges, the process
152 hands off the daemon to the <systemitem

155 <para><parameter>#EXIM_MONITOR</parameter>: This defers building the
156 <application>Exim</application> monitor program, as it requires
157 <application>X Window System</application> support, by commenting out the
158 <parameter>EXIM_MONITOR</parameter> line in the <filename>Makefile</filename>.
159 If you wish to build the monitor program, omit this <command>sed</command>
160 command and issue the following command before building the package (modify
161 <filename>Local/eximon.conf</filename>, if necessary):
162 <command>cp exim_monitor/EDITME Local/eximon.conf</command>.</para>
163
164 <para><command>ln -sv exim /usr/sbin/sendmail</command>: Creates a link to
