'''A "real" exception that developers cannot handle very well.
The difference between AppCenterError and Abort is that Abort is a
somewhat defined behavior, i.e. App installation has to fail if the
setup script fails. AppCenterError happens where it was not supposed
to.
The difference between AppCenterError and Exception is that
AppCenterError gives a nicer feedback for the Administrator than a
scary traceback. You can even put custom information into the proposed
feedback mail (raise AppCenterError(str(custom))).
As with Abort, AppCenterError should be subclassed and get a different
code.'''
