[Unison-hackers] Is this possible to have Unison not delete any files and to add only new files and modify the files...while synchronizing the files...

Hi all,
Is this possible to have Unison not delete any files and to add only new
files and modify the files...while synchronizing the files...we need
unison to have this behaviour in one of our applications.
You can give any inputs in this direction or suggest me if this is not
the way unison should work.

Regards
Hari
