I'd like to install this package:
Is it possible to do this using tlmgr?
I tried something like this, but it looks like I don't know what I am doing:
$ sudo tlmgr repository http://ctan.org/tex-archive/macros/latex/contrib/ install cookybooky tlmgr: unknown directive to tlmgr repository: http://ctan.org/tex-archive/macros/latex/contrib/
I am doing this on a macbook (TeX Live 2012).
