Predefined and user-defined type managers
Predefined type managers are provided in ClearCase®. The type managers are described in the type_manager reference page. Each type manager is implemented as a suite of programs in a subdirectory of ccase-home-dir/lib/mgrs; the name of the subdirectory is the name of the type manager.
The mkeltype –manager command creates an element type that uses an existing type manager. You can further customize DevOps Code ClearCase by creating new type managers and creating new element types that use them. Architecturally, type managers are mutually independent, but new type managers can use symbolic links to inherit some of the functions of existing ones.
