vtlib module for vt 5.3

[joebordes]

It should work, specially if it is an extension. If it is a normal module it should also work but you will be losing out on a lot of the new functionality introduced.

This small guide should still be aplicable:

just that you have to compare with the coreBOS base files.

Keep asking.
