"""
Package implementing the viewmanager of the eric6 IDE.

The viewmanager is responsible for the layout of the editor windows. This is
the central part of the IDE. In additon to this, the viewmanager provides all
editor related actions, menus and toolbars.

View managers are provided as plugins and loaded via the factory function. If
the requested view manager type is not available, tabview will be used by
default.
