The BT automatically detects the project folder using the following procedure
- check the current folder for a sc_config. Quit if current folder is root, or matches /[C-Z]:\\/
- if no, go one directory up, and repeat
- if yes, check whether the sc_config has a BT.serverConfig definition.
  - if yes, this is the project folder
