[CPS-devel] possible improvement for CPSDocument.createFile

[Florent Guillaume]

Hi Jose,

Please put this in a Trac ticket for better followups.
Also please use "diff -u createFile.py.original createFile.py" (or  
just svn diff if you work from svn) to create an easy-to-read patch.

Thanks,
Florent
