+* DEBORPHAN: get rid of "autoremove" and "removed-but-not-yet-purged" packages;
+also all packages listed in output of deborphan (only if deborphan is actually
+present, note that grml-live no longer installs deborphan by default as it's not
+present since Debian/trixie!). This class is called as such for historic
+reasons, and while deborphan itself is no longer relevant nowadays, the name of
+the class was kept as such for backwards compatibility reasons. This class is
+thought to be used *before* any further `GRML*` classes, like
+`DEBORPHAN,GRMLBASE,GRML_FULL,RELEASE,...` to get proper Grml releases.
