Great 3rd party free uv program, I recommend using the stand-alone version.
usage is simple
-import .obj model
-left click to grab edges which you want to define as borders and press C (cut)
the program will automatically use the cuts you make in the model to unwrap and layout the uvs as best it can.
it also has a texture stretching visualization mode which I recommend using.
