-The GS1 syntax engine may be added optionally.
-https://github.com/gs1/gs1-syntax-engine
-Please look to the top of makefile.vc to activate it.

-Remark, that the syntax engine dll may not be included in a starkit or zipkit.
+The GS1 Syntax Engine must be available. See the instructions in "README.linux"
+for Linux, "README.macos" for macOS, "README.bsd" for BSD, and "win32\README"
+for Windows to install.
