This is one of the central classes in the system;
|
|
|
26 |
it provides all system-startup, shutdown and maintenance support.
|
|
|
27 |
Also global variables are kept here.

As you will notice, this is NOT a Dictionary
|
|
|
30 |
- my implementation of globals is totally different
|
|
|
31 |
(due to the need to be able to access globals from c-code as well).
