Running matplotlib job with cron

Paul

Eric's attachment was missing.

This is the crontab we use, which he described:
- we use bash
- the file config/bash_env has most of what is usually in .bashrc;
  for cron we source it, for shell we source it in .bashrc
- "daily.py --use_defaults" is the command that we want to run
- don't forget that early inclusion of
  matplotlib.use('Agg')

## here is the relevant part of crontab
# m h dom mon dow command
40 20 * * * (cd $HOME; . config/bash_env; daily.py --use_defaults) > $HOME/tmp/cron.log 2>& 1
