comment in a file but none of the actual code.</para>

<para>One of the following variables (but not both) should be set if
the source directory is different from the build directory. If the
build directory is simply a subdirectory of the source directory, the
simpler variable <envar>OBJ_SUBDIR</envar> should be used. </para>
<variablelist>
<varlistentry>
<term><envar>OBJ_SUBJDIR</envar></term>
<listitem><para>Indicates that the build directory is in the given subdirectory of the source directory. For instance, if the source directory is <filename class="directory">kdesdk</filename> and the build directory is <filename class="directory">kdesdk/obj-i386-linux</filename>, then <envar>OBJ_SUBDIR</envar> should be set to <parameter>obj-i386-linux</parameter>.</para></listitem>
