I did a PackageVersion class that parses these sections using a |
| 20 |
regular expression following the package naming policy. I don't send |
| 21 |
the code since I'll need to recode it, my XFS lost many data after a |
| 22 |
power failure :( But I have the bytecode if you want to test it or |
| 23 |
help me to get the .py back. |

Gentoo uses separated kernel sources, I use Con Kolivas source, it's |
| 36 |
ck-sources in the tree. |
