+
+This directory contains Boost.Build examples for the Qt library
+(http://www.trolltech.com/products/qt/index.html).
+
+The current examples are:
+  1. Basic setup -- application with several sources and moccable header.
+  2. Using of .ui source file.
+  3. Running .cpp files via the moc tool.
+
+For convenience, there are examples both for 3.* and 4.* version of Qt, they are
+mostly identical and differ only in source code.
+
+All examples assumes that you just installed Boost.Build and that QTDIR
+environment variables is set (typical values can be /usr/share/qt3 and
+/usr/share/qt4). After adding "using qt ..." to your user-config.jam, you would
+have to remove "using qt ; " statements from example Jamroot files.
