Don't know if you have ran into this yet.
LibreOffice 4.x is python 3.0 based on Mac OS X
Appy tosses syntax errors:
Traceback (most recent call last):
appy.pod.PodError: An error occurred during the conversion. File "/Library/
except (OSError, IOError), ioe:
SyntaxError: invalid syntax
Works fine with LO 188.8.131.52 which is python 2.6.1.
Thank you for all your work on Appy.
