+        PHP considers each path in the include path seperately when looking for
+        files to include. It will check the first path, and if it doesn't find
+        it, check the next path, until it either locates the included file or
+        returns with a 
+        <link linkend="errorfunc.constants.errorlevels.e-warning">warning</link>
+        or an <link linkend="errorfunc.constants.errorlevels.e-error">error</link>. 
+        You may modify or set your include path at runtime using
+        <function>set_include_path</function>.
