Sally does a pull and finds something that makes her mad as a mule chewing on bumblebees.

Sally remembers that the specification says the product isn’t supposed to include a full email reader until the next release. For the entire 1.0 development cycle, that third party library is going to be about as useful as a snooze button on a fire alarm. So she deletes it.

lottery sally$ vv rm libvmime-0.9.1 

lottery sally$ vv commit -m "no mail reader until 2.0"
