+<emphasis role="strong">Automatic moc file generation from header files.</emphasis>
+You do not have to specify moc files explicitly, the tool does it for you.
+However, there are a few preconditions to do so: Your header file must have
+the same filebase as your implementation file and must stay in the same
+directory. It must have one of the suffixes .h, .hpp, .H, .hxx, .hh. You
+can turn off automatic moc file generation by setting QT_AUTOSCAN to 0.

+<emphasis role="strong">Automatic moc file generation from cxx files.</emphasis>
+As stated in the qt documentation, include the moc file at the end of
+the cxx file. Note that you have to include the file, which is generated
+by the transformation ${QT_MOCCXXPREFIX}&lt;basename&gt;${QT_MOCCXXSUFFIX}, by default
+&lt;basename&gt;.moc. A warning is generated after building the moc file, if you
+do not include the correct file. If you are using VariantDir, you may
+need to specify duplicate=1. You can turn off automatic moc file generation

+The implementation files generated from .ui files are handled much the same
+as yacc or lex files. Each .ui file given as a source of Program, Library or
+SharedLibrary will generate three files, the declaration file, the
+implementation file and a moc file. Because there are also generated headers,
+you may need to specify duplicate=1 in calls to VariantDir.
