 For example, to generate a pb_type xml file from adder.v, run 
 
 ```
-python -m v2x -o adder.pb_type.xml adder.v
+v2x -o adder.pb_type.xml adder.v
 ```
 
 Or, to generate a model xml file, run 
 
 ```
-python -m v2x --mode model -o adder.model.xml adder.v
+v2x --mode model -o adder.model.xml adder.v
 ```
 
 v2x expects the module name to be the same as the file name. If it is different, make sure to specifiy it with the `--top` argument.
 
 ```
-python -m v2x --top BLOCK -o adder.pb_type.xml adder.v
+v2x --top BLOCK -o adder.pb_type.xml adder.v
