Description.ext RscTitles using them in scripts

[Nedal]

i have read a tutorial about classes in description.ext from DevilDawn,

but there is a mission from OYC Tournament, where these classes defined in description.ext are used in intro.sqs script.

i wana build an intro similar with lots of different texts, using the same class.

but i dont know how to make a class in description.ext wich can be used in intro.sqs scripts.

can anyone help?
