Camera in MakeHuman

The camera is referenced a number of times in MakeHuman:
- In the "mhm" files saved by MakeHuman, there is a line that starts with "camera" and holds six floats. What are these numbers?
- There is a function "MHScript.printCameraInfo()" callable by scripts that outputs a bit of information. This information does not seem to actually depend on the camera, as it does not change when the camera is changed.
- The object "cam" offers a function "getMatrices()" which does print a couple of matrices. What are these matrices?
