this can do it nicely.

+From: Sebastián Mancilla <smancill@smancill.dev>
+Subject: Update SVMlight scrubber script
+
+This requires previously fixing a few wrong preprocessor directives that
+are supposed to fence code using SVMlight.
+
+- The script was too eager and removing *.light files in SVMlight format
+  that are used by other tests. The code reading those files doesn't use
+  any SVMlight code so it should be fine to keep it and run the tests.
+
+- The Python test *domainadaptationsvm.py was not removed because of
+  wrong globbing.
+
+- Remove a couple of examples using SVMlight that were missed.
+
+- The script is actually modifying (and breaking) itself because the
+  grep for the USE_SVMLIGHT macro is too eager again and matches itself
+  (and the version stored in upstream's Debian package control tarball
+  is broken because of it). Just fix it by grepping for preprocessor
+  directives only.
+
+- No need to fix the Transfer_includes.i file in the script with a final
+  %} when its preprocessor directives have been fixed.
+
+- The Swig files were moved to a new directory at some point but the
+  script was not updated accordingly.
