Hi, |

first I should note that I'm not involved with the development of |

portage so take everything I write with a good grain of salt ;) |

I assume you mean only the stuff the user has overridden, not collapsed |
| 14 |
together with the corresponding files in the profiles? |

As I had a few minutes of spare time, and I'm much better at writing |
| 25 |
code than explaining stuff I hacked together a small script that |
| 26 |
showcases the API's I would use to get at the above data. (see |
| 27 |
attachment) |

Unless I forgot something, or made some stupid mistake all of them ;) |

As you can see in the attached script, most of the interesting stuff is |
| 38 |
either available through a portage.config instance, or via the |
| 39 |
applicable dbapi (porttree for anything that can be installed, vartree |
| 40 |
for anything regarding installed packages, etc.) |
| 41 |
