Typing 'make micaz sim' will generate app.xml. Please read the  
section "Compiling TOSSIM" of the tutorial. You should see this in  
our compilation output:

           mkdir -p build/micaz
             placing object files in build/micaz
             writing XML schema to app.xml
             compiling BlinkAppC to object file sim.o

Note the third line: "writing XML schema to app.xml."

You need to be in the directory with app.xml, so the Python code can  
read it in to figure out what variables your application has.
