Bugzilla, it does not refer to users by their user names, but by their unique
userid, stored as a primary key in the profiles table.
-components: This stores the programs and components (or products and
-components, in newer Bugzilla parlance) for Bugzilla. Curiously, the "program"
-(product) field is the full name of the product, rather than some other unique
-identifier, like bug_id and user_id are elsewhere in the database.
+components: This stores name, the description and initial
+owner/qacontact of the component, and to which product the components
+belong.
dependencies: Stores data about those cool dependency trees.
