[Opensim-dev] About BML Script

[PEISEN ZHAO]

Hello everyone,
I have a question about the BML script. I am trying to write some bml code such that the person in the OpenSim can run and do what the code ask it supposed to do. However, I have not idea where to start this hacking. I have downloaded the OpenSim project. But I can not find any file about BML. What's more, what should I do to allow the opensim to run the script?

Thank you so much for your help.
Philip
