+	# - .CreationID
+	# - .Revision
+	# - .VersionID
+	# - SystemFiles/Installtion/wolfram-mathematica12.desktop (dynamically generated, contains $pkgdir)
+	# - (sometimes) InstallErrors
+	# These files seem to be used by the installer to detect the version of an older installation.
+	# For the sake of convenience we omit them here.
+	# The WolframEngine installer uses Makeself, whose version unfortunately does not support the --noexec option.
+	# So we have to hard code the number of lines (388) here and extract the data manually.
