+GS1 - l3-package for handling of GS1 codes of GS1 specification
+----------------------------------------------------------------------------
+Maintainer:	Markus Kohm
+E-Mail:		komascript at gmx info
+Abstract:	Currently the package is able to
+		- calculate control digits for EAN-8 and EAN-13
+		- generate bar code for EAN-8 and EAN-13
+Requires:	expl3  - stable packages of LaTeX3 kernel for LaTeX2e
+		xparse - definition of LaTeX2e user commands using LaTeX3
+		rule-D - see below
+License:        LPPL 1.3c or later
+State:          Author maintained
+============================================================================
+rule-D - l3-package simply providing LaTeX3 \rule functions
+----------------------------------------------------------------------------
+Maintainer:	Markus Kohm
+E-Mail:		komascript at gmx info
+Abstract:	Currently there's no \rule command in expl3, but GS1 needs
+		it.
+Requires:	expl3 - stable packages of LaTeX3 kernel for LaTeX2e
+License:	LPPL 1.3c or later
+State:		Author maintained
