Qt is a cross-platform application framework for desktop and
embedded development. Qt enables programmers to create advanced GUI
applications once and deploy them to Windows, Mac OS X and Linux without
rewriting the source code. Companies using Qt can leverage software
investments made on one platform across many others.

This is a test release of what is expected to be the last Qt5 version
available from upstream.  Please report any discrepancies from earlier
Cygwin-available Qt5 packages.  If all seems well, this version will
probably be promoted from test in a couple weeks.
Enjoy,

PS: h/t to Achim for his Qt5 updating work that I've built upon.
