If I remember correctly, the code does this : pkg1 : extract files ; write db entry pkg2 : extract files ; write db entry etc ..

Otherwise, go go sqlite :) _______________________________________________ pacman-dev mailing list [email protected] http://www.archlinux.org/mailman/listinfo/pacman-dev
