The idea is to make an ipython 'profile' with the contents indicated in the
manual.  IPython profiles are explained here:


So let's say that you want to make a profile called 'autolog' using Robert's
trick.  You would then need to make a file named


which would contain:

include ipythonrc
logfile '' # cancel earlier logfile invocation
execute import time
execute __cmd = 'PUT_SOME_PATH_YOU_WANT_HERE-%s.log rotate'
execute __IP.magic_logstart(__cmd % time.strftime('%Y-%m-%d'))

Then, you'd simply call ipython using this profile as

ipython -p autolog

at the command line.  If you end up using this very frequently, you can alias
it witha convenient name of your choosing.

I hope this helps.
