Currently, I am editing my production server's crons by typing `crontab -e`.
I would like to store my crontab definitions inside my project, and have my system to load them from there. 

Is there any way I can set up the servers existing crontabs to point to an include like this? 

`IncludeOtherCrontab /path/to/my/project/project.crontab`

My system is CentOS release 5.4 (Final)
