it’s not simple thing if you use pip to
install pyside. Make sure you have
installed qt dev package.

4. How to use it?
if __name__ == '__main__':
map = CallSeq()
map.set_trace()
test()
map.unset_trace()
map.dump_to_file('output.json')

5. How to use it?
@trace('output.json')
def main():
test()

6. How to use it?
if __name__ == '__main__':
with CallSeq(name='output.json'):
test()

7. How to use it?
$ python -m call_seq.core output.json demo1.
py

8. How to use the file the tool
generate?
$ python -m call_seq.browser output.json

9. Source code is displayed
here.
function `default_hook` is
defined here. The line is
marked with gray.
We can know that the
function `__init__` call
`default_hook` and store
result in `self.hooks`
We can know that
`default_hook` return in line

dict with key `response`.
We can know the function get
