+ <listitem>
+ <para>You can select alternative suffixes for object files and
+ interface files, so you can have several builds of the same
+ code coexisting in the same directory. For example, to
+ compile with profiling, you might do this:</para>
+
+ <screen>ghc --make -prof -o foo-prof -osuf p.o -hisuf p.hi Main</screen>
+
+ <para>See <xref linkend="options-output"> for more details on
+ the <option>-osuf</option> and <option>-hisuf</option>
