"""Script to process UI files (convert .ui to .py).
It compiles .ui files to be used with PyQt4, PyQt5, PySide, QtPy, PyQtGraph.
You just need to run (it has default values) from script folder.
To run this script you need to have these tools available on system:
- pyuic4 for PyQt4 and PyQtGraph
- pyuic5 for PyQt5 and QtPy
- pyside-uic for Pyside
- pyside2-uic for Pyside2
Links to understand those tools:
- pyuic4: http://pyqt.sourceforge.net/Docs/PyQt4/designer.html#pyuic4
- pyuic5: http://pyqt.sourceforge.net/Docs/PyQt5/designer.html#pyuic5
- pyside-uic: https://www.mankier.com/1/pyside-uic
- pyside2-uic: https://wiki.qt.io/Qt_for_Python_UiFiles (Documentation Incomplete)
