130 <para><command>sed -e ... > Local/Makefile</command>: Most of
131 <application>Exim</application>'s configuration options are compiled in using
132 the directives in <filename>Local/Makefile</filename> which is created from
133 the <filename>src/EDITME</filename> file. This command specifies the minimum
134 set of options. Descriptions for the options are listed below.</para>

143
144 <para><parameter>EXIM_USER=exim</parameter>: This tells
145 <application>Exim</application> that after the daemon no longer needs
146 <systemitem class="username">root</systemitem> privileges, the process
147 hands off the daemon to the <systemitem
148 class="username">exim</systemitem> user.</para>

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