|

|
* The ASF file consists of code blocks that are called content objects. Each
|

|
* of these objects have a format of their own. They may contain other objects
|
||||||
|
* or other specific data. Each supported object has been implemented as their
|

|
* own classes to ease the correct use of the information.
