akonadi-backend-mysql 1.7.2-0ubuntu1 (i386 binary) in ubuntu precise

 Akonadi is an extensible cross-desktop Personal Information Management (PIM)
 storage service. It provides a common framework for applications to store and
 access mail, calendars, addressbooks, and other PIM data.

 This package installs everything what's needed for Akonadi to work with MySQL
 as underlying data storage engine. By default, a local MySQL server instance
 will be started for each user. Alternatively, connection to an external MySQL
 database is supported as well.
