Is there a variable I can utilize that references the root of the project?

[paulcalabro]

I have a base config that specifies playbooks for destroy, create, converge, and verify actions.
Those playbooks are in <project_root>/extensions/molecule/resources/playbooks.
I also have roles at <project_root>/roles and each role within contains a molecule directory that contains a molecule.yml. These configs are merged with the base config.

Is there a variable that I can use to refer to the root of the project so I don't need use relative paths for the paths to those playbooks in the base config (i.e. avoid .../../playbooks/create.yml)?
