MErge texture? how do u use>?

[WAKA-WAKA]

hi all,
i have been texturing a model with different textures, and where the different textures meet i just cant get them to blend together well on the unit. i came across the MERGE Textures button under the surfaces tab in 02, and that sounds like it might be what i am looking for. but i dont know how to use it1 it requires a script or somthing.
anybody know what to do?
