[Bf-extensions-cvs] SVN commit: /data/svn/bf-extensions [2315] trunk/py/scripts/addons/modules/ extensions_framework/util.py: extensions_framework: add getSequenceTexturePath function to utils module

[Campbell Barton]

best replace "/" with os.sep, but generally, I'm not sure its a good
idea to duplicate this code in python, think its worth looking into
how blender does it and adding a call in bpy.paths which re-uses C
code.
