Usage:

1. Add/Remove ruby variables to cron:

   rvm cron {setup|remove}

2. Manage rvm on single command level

   rvm cron command <"schedule">

   Example 1 set one ruby for all cron jobs:

   cd /project/dir  # go to project dir, or `rvm use ...`
   rvm cron setup   # initialize cron with ruby settings
   crontab -e       # add tasks to cron
   

   After project ruby changes:

   rvm cron setup   # update cron with new ruby settings
   

   Example 2 add single job using current dir for rvm:

   cd /project/dir  # go to project dir, or `rvm use ...`
   rvm cron command "@daily" rake calculate:stats
   

   Refer to man 5 crontab for definitions of time/date, examples:

   "*/5 * * * *" - Every 5 minutes
   "@hourly"     - Once an hour
   "* */4 * * *" - Every 4 hours
   "0 6 * * *"   - Everyday at 6am
   "0 7 * * 5"   - Every Friday at 7am
   

   NOTE! Do not forget to set notification email in crontab -e:

   MAILTO=someone@project.com
