First of all kudos for making this project available as so robust. I have been developing similar solution myself based on markdown - but this one is way better.

With that said - I am missing one thing that made me start my own project - filtering.

It would be useful for quick generating a cv tied to a specific role. I.e. if I am replying to python developer offer - I would only want my experience with development, not necessarily with financial software or pharmacy.

I am imagining yaml file extended like so:

sections:
    education:
      - institution: Princeton University # developer
        area: Computer Science (...)
      - institution: Boğaziçi University # medical
        area: Computer Engineering (...) 

and command to optionally accept a parameter list at the end:

rendercv render ./foo.yaml medical gastronomy (...)

in which case only untagged sections and sections with specified tags would be included for rendering.

I am willing to participate in developing this, let me know if this is something that you see PR-worthy.
