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

141 <application>Exim</application>'s binaries and scripts in

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

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