Control acccess to applications and individual updates.

Control the distribution of your update packages. By assigning Access Lists, you

packages and new software versions.
Using lists, you can easily distinguish between Development, Quality Assurance,

groups of clients that are eligible for updates and those that are not. The possibilities
