This version of PyQwt includes the Python wrappers around the QwtPolar C++ library.
The C++ sources of version 5.2.0 of Qwt have been combined with version 0.1.0 of QwtPolar
and the appropriate .sip files created to create the unified Python wrapper.
Installation is the same as for Qwt, see: http://pyqwt.sourceforge.net/doc5/index.html
Two demos are include in the qt4examples directory in the tarball.
Perhaps in the future Qwt6 will include QwtPolar.
