9# The main purpose of this module is to import Gtk+2 or 3 and related modules
10# and provide common names for them. There is a similator module in the GUI
11# part (\ref mlx.gui.common), which contains the GUI-specific names. This one
12# contains only what is used by other modules as well.
13# The variable \c pygobject tells which version of Gtk is being used. If it is
14# \c True, Gtk+ 3 is used via the PyGObject interface. Otherwise Gtk+ 2 is
15# used, which is the default on Windows or when the \c FORCE_PYGTK environment
16# variable is set.
