How to use bzr inside a python script.

[Mariano Mara]

Hi everyone,
 I wrote this Python script that basically connects to an Oracle schema, 
retrieves the whole model and then creates a DML script (let's call it 
output.sql) that can be use to install elsewhere the schema. I want 
output.sql to be versioned with bzr and for that users have an option in 
case they want to commit the new output.sql into a branch.
My doubt is: how can I call bzr commands from within the python script? 
Can I use it as a imported module? If so, how? or do I need to use it  
as command lines commands?

If you can point me to some documents addressing this kind  of 
information, I'll appreciate it.
Regards
