Hello,

I provide these scripts to put your /var/db/pkg tree back to a
compatible state after all the slots adventures.

First run convertslot.sh and then convertslots2.py, afterwards your
installed package tree should be compatible with 1.8.8 again and with
what slots are supposed to become in the next revisions.

Happy gentooing ! 

Geert
