For general information on LKRG, please visit its main wiki page.
This wiki page used to describe and provide examples for so-called “Protected Features” of experimental branch of LKRG, which has since been abandoned. The content of this page dated back to 2017-2018 (that is, prior to or around LKRG 0.0 release), and was finally dropped in 2020 as it was more confusing than useful.
