If you’re already maintaining a decent Sitecore Blogroll you know this. But in case this blog has escaped your attention, I think you need to take a look at this:
Check your packages with PCheX
As someone who often designs update packages and mail them off to clients, I am sure this tool will quickly make it to the top of my list of favourite tools and save me a lot of hassle.
The description says it all lol… 
“In a way, you can imagine PCheX to be like a little friendly elf who comes around and kindly whacks you around the head with a big rubber hammer if you design an unhealthy package. “
And we certainly don’t want to get whacked by big rubber hammers do we?
