what is the way python-interface connect to linuxcnc-command?

Hi,

I see linuxcnc-command has some functions that python-interface doesnt have. I want to link them to python-interface. It seems relative to classes in emc_nml.hh file (github.com/LinuxCNC/linuxcnc/blob/master.../nml_intf/emc_nml.hh) but i cant find the way classes is used. I tried create an abs_jog function in emcmodule.cc(github.com/LinuxCNC/linuxcnc/blob/master...ensions/emcmodule.cc) that has similar format to increment_jog and it worked

Can someone point me which files should i see to make sure my new functions will work? For now, i want to create a function that can set acceleration
