"""
Py2app support for project using sip, which basicly means PyQt and wrappers
for other Qt-based libraries.
This will include all C modules that might be used when you import a package
using sip because we have no way to fine-tune this.
The problem with SIP is that all inter-module depedencies (for example from
PyQt4.Qt to PyQt4.QtCore) are handled in C code and therefore cannot be
detected by the python code in py2app).
