[chef] Omnibus post-install script

[Michael Hayes < >]

https://github.com/hayesmp/omnibus-rumm

I am using omnibus-ruby to create a package to install our command-line 
tool/gem rumm. What I would like to do is to either symlink the gem 
executable to /usr/local/bin or add the /opt/rumm/emedded/bin/rumm to PATH.

Is there a method in omnibus to run post-install scripts? Adding anything to 
'build' step won't run when package installs. I apologize for my ignorance on 
how all this works...
