PyQt/PySide compatibility layer for Qt4/Qt5/Qt6.

 The package allows the programmer to program equally for two different
 versions of Qt:
  * At the top level AnyQt exports a Qt5 compatible module namespace along with
    some minimal renames to better support portability between different
    versions
  * Which Qt API/backend is chosen can be controlled by a QT_API env variable
  * The api can be chosen/forced programmatically (as long as no
    PyQt4/PyQt5/PySide/PySide2 was already imported)
  * Provides an optional compatibility import hook, that denys imports from
    conflicting Qt api, or intercepts and fakes a Qt4 api imports, to use a Qt5
    compatible API (some monkey patching is involved).
 .
 This is the AnyQt documentation package.
