Your packages are great! However, it would be a nice feature to have
some sort of "recompile.conf" file that could be used for upgrades. I
chenged most of my db's to skiplist before I got things working. Now, if
I recompile without thinking (a bit stressed for some reason) I might
just happen to create loads of work. Therefore it would be nice to have
a simple way to keep settings between version - unless you realy want to
change things.
