+% Since version 1.40.0 \pdfTeX\ has \cs{pdfprimitive} and
+% \cs{ifpdfprimitive}. And \cs{pdfprimitive} was fixed in
+% version 1.40.4.
+%
+% \XeTeX\ provides them under the name \cs{primitive} and
+% \cs{ifprimitive}. \LuaTeX\ knows both name variants,
+% but they have possibly to be enabled first (|tex.enableprimitives|).
+%
+% Depending on the format TeX Live uses a prefix |luatex|.

+% the macros, especially because of \cs{ifpdfprimitive}.
