commit c1d3e192561691b5e14e739ccb86a8e68137723c

    Python script to parse build.lst and generate dependency list.
    
    The dependency output is dot compatible format, so you can run it
    as follows:
    
    ./check-deps.py > deps.dot
    dot -Tpng deps.dot -o deps.png
    
    to create a dependency graph in png format.
