-    Since the \c debug option overrides the \c release option when both are
-    defined in the \c CONFIG variable, it is necessary to use the
-    \c debug_and_release option if you want to allow both debug and release
-    versions of a project to be built. In such a case, the Makefile that
-    qmake generates includes a rule that builds both
-    versions, and this can be invoked in the following way:
+    When you use the \c debug_and_release option (which is the default under
+    Windows), the project will be processed three times: one time to produce
+    a "meta" Makefile, and two more times to produce a Makefile.Debug and a
+    Makefile.Release.
+
+    During the latter passes, \c build_pass and the respective \c debug or
+    \c release option is appended to \c CONFIG. This makes it possible to
+    perform build-specific tasks. For example:
+
+    \snippet code/doc_src_qmake-manual.pro 25
+
+    As an alternative to manually writing build type conditionals, some
+    variables offer build-specific variants, for example
+    \l{#QMAKE_LFLAGS_RELEASE}{QMAKE_LFLAGS_RELEASE} in addition to the general
+    \l{#QMAKE_LFLAGS}{QMAKE_LFLAGS}. These should be used when available.
+
+    The meta Makefile makes the sub-builds invokable via the \c debug and
+    \c release targets, and a combined build via the \c all target.
+    When the \c build_all \c CONFIG option is used, the combined build is
+    the default. Otherwise, the last specified \c CONFIG option from the set
+    (\c debug, \c release) determines the default. In this case, you can
+    explicitly invoke the \c all target to build both configurations at once:
 
     \snippet code/doc_src_qmake-manual.pro 24
