Qt development files
 Qt is a C++ class library optimized for graphical user interface
 development. This package contains libqt-mt.so symlink, necessary
 for building threaded Qt applications.
 .
 WARNING: The nonthreaded version of Qt3 is considered deprecated and
 may disappear anytime in the future. Please use libqt3-mt-dev instead
 (Read README.Debian for instructions).
 .
 WARNING 2: If you plan to build some older Qt3 applications, you will
 most probably have to install the libqt3-compat-headers package. It
 contains all the headers which are not part of the official Qt3 API
 anymore but which are still used by some programs. So if you encounter
 problems with missing header files, please install this package first
 before you send a bugreport.
