Addresses issue where you dont want any further new installs of a product, yet you want existing versions to get happily patched if required.

Example

Create repo with blacklist tag, blacklisting ImageMagick and microsoft

$ sudo createrepo --content=blacklist:^ImageMagick,^microsoft /var/www/html/repo
