IPython Packaged with CIAO OTS
CIAO includes IPython in the CIAO OTS directory which is used by Sherpa and ChIPS to provide command-line user interfaces. These programs create an IPython profile in the directory $HOME/.ipython-ciao, as to not override the user's IPython setup should one already exist.
If IPython users want any personal customizations to be available when running CIAO, they will have to copy them from $HOME/.ipython to $HOME/.ipython-ciao. Alternatively, the environment variable IPYTHONDIR to $HOME/.ipython, in which case, CIAO will use that as the default IPython directory.
