[Orgmode] Automatically move completed TODO items and checkboxes to another file

[Michael Hoffman]

I have happily been using org-mode for many years to keep a todo list. I 
like keeping a log of the actions I've completed, but I don't like them 
in the same file taking up space. Previously I have moved completed TODO 
items and checkboxes to another log file manually. Is there a good way 
of doing this automatically? Do you have any other suggestions for how 
to keep a log of done tasks while removing the cruft left over from the 
current list?
