Have a look at the examples.

Installation

You can find detailed installation instructions here: install.org.

Performance

As some of the processes might be quite memory-consuming, it is recommended to adjust the dynamic heap size of SBCL, e.g.

sbcl --dynamic-space-size 8192
# this is setting the maximum heap size to 8192 MB

Compatibility

Tested with SBCL on MacOS and Linux (Ubuntu 22.04).
