[pacman-dev] dbscripts status

[Xavier]

Why are there so many files there :
http://projects.archlinux.org/git/?p=dbscripts.git;a=tree

pkgdb, pkgdb1, pkgdb2-add.c, pkgdb2-del.c, pkgdb2.c, updatesync-many.
These names don't really speak to me.
Is updatesync-many the only one developers use directly? And what are 
all the pkgdb* stuff for?
Well, at least the three c programs seem to interact with the mysql 
database.
But that doesn't explain how all the scripts / programs interact 
together, and how hard it would be to make them use repo-add instead.
