 """Generator for C++ structs from api json files.
 
 The purpose of this tool is to remove the need for hand-written code that
 converts to and from base::Value types when receiving javascript api calls.
 Originally written for generating code for extension apis. Reference schemas
 are in chrome/common/extensions/api.
 
 Usage example:
   compiler.py --root /home/Work/src --namespace extensions windows.json
     tabs.json
   compiler.py --destdir gen --root /home/Work/src
     --namespace extensions windows.json tabs.json
