gs1
package.
Summary description: GS1 codes and bar codes (currently EAN-8 and EAN-13 only) using expl3 License type: lppl
Announcement text: ----------------------------------------------------------------------
GS1 started to handle codes specified by the GS1 specification. It can generate the control digits of some GS1 codes and some bar codes corresponding with the GS1 codes. It depends on stable expl3 packages and the sub-package rule-D only.
There's an additional sub-package rule-D, that provides L3 functions ule:nn and ule:nnn similar to LaTeX2e ule command.
