Title       : 	Ubuntu/Debian update mailer

This is a bash script for Ubuntu and Debian, to be run by cron on a set
interval. It checks if there are apt-updates, and if so, mails an overview of
the packages which can be updated, whith their local version, the version
available and an URL to the Ubuntu package site where you can see the changelog.
I wrote this as an addition for my Nagios monitoring, that only shows how many
updates there are, this is a lot more verbose. It also runs on Debian since 1
Nov 2012. Only the links don't work then, because the packages are different.

I'm developing an open source monitoring app called Leaf Node Monitoring, for windows, linux & android. Go check it out!

Consider sponsoring me on Github. It means the world to me if you show your appreciation and you'll help pay the server costs.

You can also sponsor me by getting a Digital Ocean VPS. With this referral link you'll get $100 credit for 60 days.

#### Example output:
If there are no updates:
    
    
    No updates available for host vps11.sparklingclouds.nl on date 21.09.2012
    
If there are updates:
