The libraries included here are the original packages, unpacked, and
with their version number removed from the directory name (for version
information, see the README files in the directories).  The following
have been removed:
 
    libjpeg - some source files, images, Makefiles, manual pages
    libpng/contrib - a collection of examples and test-suite
    zlib/contrib - a collection of non-zlib code
    zlib/msdos - Zlib for a platform never supported by Qt ;-)
    zlib/old - Zlib for other platforms not supported by Qt ;-)
    libmng/contrib - ?
    libmng/special - ?
    sqlite/* - only the source files have been copied over

Some patches are applied from time to time.
