-If you want more complex operations than offered by the command line or GUI tools, you can manipulate BINoculars data directly from Python. Some examples with detailed comments can be found in the [repository](https://github.com/id03/binoculars/tree/master/examples/scripts). The API documentation on the `BINoculars` and `BINoculars.space` modules can be accessed via pydoc, e.g. run `pydoc -w BINoculars BINoculars.space` to generate HTML files.
