[arch-dev-public] devtools-0.6.4 release

[Allan McRae]

Hi Devs,

I just pushed the new devtools to [testing].  The major thing in this 
release is that in combination with the new db-scripts your staging 
directory only needs to look like staging/{core,extra,testing}.  No need 
for *64 directories (get that from the package name) and add/del 
directories are no more (db-remove is used for removing packages now).
