_Matthias Gondan, Department of Psychology, Universität Innsbruck, Austria_

Supported by the Erasmus+ programme of the European Commission, 2019-1-EE01-KA203-051708

The purpose of this package is to embed SWI-Prolog (https://www.swi-prolog.org,
https://github.com/SWI-Prolog/swipl-devel/) into an R library, such that other packages
can link to the SWI-Prolog runtime without the need to install the program on their
computer. This R package is *not* meant to be used directly. Please use the
R\ package `rolog` instead. Install this package if you do not have the administrative
privilege to install SWI-Prolog on your computer.

## License

distributed under its own license (BSD-2).
