I implemented something similar in commit
45aba232abe50b6642abfaa06030985c7febbe07.

There still are problems, though.  The program expects a directory
“Songs” to exist in the current working directory.  It then fails with
this error:

    Error: No NoteSkins found

This seems to work fine only when when “stepmania” is executed from
within the “share/stepmania” directory.  I suspect that this is the same
kind of problem.
