how to read ipa source code#ironic-python-agent

Hi~ I have an OpenStack platform on Rocky, and I used Nova/Keystone/Cinder/Glance/Ceph/Ironic. Recently, I have build my own ironic-python-agent deployment ramdisk and kernel images by ironic-python-agent-builder, the following work is to add my customized raid configuration method to HardwareManager. Before this, I want to read the ipa's source code. But I don't know where is the 'main()' entry. Looking forward to your help.
