The functionality of testdb is now available in pacman. pacman -Dk will
check the local database for consistency, and pacman -Dkk will check the
sync databases.
Note that unlike testdb, you can not specify individual sync databases to
check as sync databases act as a whole and not individually. A single database
can be checked using an alternative pacman.conf file.

VERSION DESCRIPTION
-----------------------------------------------------------------------------
+5.0.0 - pacman can check the validity of the local and sync databases
+ (-Dk and -Dkk respectively). This replaces the 'testdb'
+ software
4.2.0 - symlinks to directories on the filesystem are no longer
treated as directories
- pacman-db-upgrade - fix local database for files installed
