Directory for user data “PYRPL_USER_DIR”

By default, PyRPL will search the home folder “HOME” of the user and create the folder “HOME/pyrpl_user_dir”. This folder contains three subfolders:

• config for the PyRPL configuration files of the user.

• lockbox for custom lockbox scripts, similar to the files “interferometer.py” or “custom_lockbox_example.py”.

• curve for saved curves / measurement data.

By setting the environment variable PYRPL_USER_DIR to an existing path on the file system, the location of the PyRPL user directory can be modified. This is useful when the user data should be syncronized with a designated github repository, for example.
