If there's not a native way to do it, you could have a "loader" program 
start the main program. When the main program terminates, control would 
be returned to the loader program, which would check an update directory 
for an update. If it finds one it would overwrite the main program with 
the update, delete the update, then re-run the main program. If not it 
would just exit normally. I'm going to need to do this myself at some 
point with my application.
