is a snapshot.  I will only do some minor packaging tweaks
before releasing.

PyQwt-5.0.1a/qwt-5.0 is a SVN snapshot which is a
bit more recent than the latest official release Qwt-5.0.2.

In principle, all you have to do is edit

1. comment out the line
CONFIG           += QwtDll
(should produce a static lib)

2. uncomment the line
#CONFIG     += QwtSVGItem
(so that Qwt can export its graphs to SVG)

and run qmake, etc..

I think you shouldn't do anything special to build the Qwt
designer plugin, but ..

The Qwt documentation is at
The complementary documentation for PyQwt is at

The tarball contains all documentation, see
PyQwt-5.0.1a/configure/PyQwt.nsi.in, if you
decide to include it in your package.

Once you have the static Qwt library you can build PyQwt from
the PyQwt-5.0.1a/configure directory:

python configure.py -I qwt-header-dir -L qwt-lib --disable-numpy
(python configure.py --help)

and run make and make install

To run the quite a few examples (eg. ReallySimpleDemo.py) you
need to install numpy (PyQwt plots also data consisting of lists
and tuples, but slower than numpy arrays).  The --disable-numpy
prevents that the PyQwt build finds numpy so that PyQwt does
not try to import numpy.  However, PyQwt can still copy data out of
numpy arrays but is independent of a particular version of
numpy (or recent versions of its predecessors -- Numeric and
numarray -- if users can choose what they like).

A numpy exe is at

PyQwt install a module iqt which has become superfluous
(PyOsInputHook) with PyQt4 and some other python modules
which are probably not very useful on windows (qplt.py and grace.py).


PS: PyQwt builds on 64 and 32bit Linux with your latest snapshots
and on 32bit Windows with your latest GPL releases (did not test
the snapshots)
