The easiest way is to wrap your python script in a shell script. This
would be necessary* if using virtualenv. Mine look like this (from
rote, so may be wrong):

  #!/bin/sh
  . /path/to/django/install/my-venv-name/bin/activate
  DJANGO_SETTINGS_MODULE=myproj.settings
  export DJANGO_SETTINGS_MODULE
  # virtualenv activate ensures we get right python
  python /path/to/django/install/myproj/manage.py foobar "$*"


You can then put this directly into cron:

@daily /path/to/wrapper.sh "bar" "quuz wibble"

Cheers

Tom

* well, easier. Maybe not necessary
