+
+    <para>
+
+    Sometimes SCons doesn't build the target you want
+    and it's difficult to figure out why.  You can use
+    the <literal>--debug=prepare</literal> option
+    to see all the targets &SCons; is considering, whether
+    they are already up-to-date or not. The message is
+    printed before &SCons; decides whether to build the target.

+
+    <para>
+
+    When using the &Duplicate; option to create variant dirs,
+    sometimes you may find files not getting copied to where you
+    expect (or not at all), or files mysteriously disappearing.  These
+    are usually because of a misconfiguration of some kind in the
+    SConstruct/SConscript, but they can be tricky to debug.  The
+    --debug=duplicate option shows each time a variant file is
+    unlinked and relinked from its source (or copied, depending on
+    settings), and also shows a message for removing "stale"
+    variant-dir files that no longer have a corresponding source file.
+    It also prints a line for each target that's removed just before
+    building, since that can also be mistaken for the same thing.
