l3keys2e – LaTeX 2e op­tion pro­cess­ing us­ing LaTeX 3 keys

The pack­age pro­vides an in­ter­face whereby LaTeX 2e users may use the key-value func­tions pro­vided in the LaTeX 3 ker­nel dis­tri­bu­tion.
The key-value sys­tem im­ple­mented is more sim­i­lar to that of pgfkeys than to any other ex­tant pack­age.
The pack­age on CTAN de­rives from a snap­shot of the LaTeX 3 repos­i­tory, taken on 2012-07-16, and is dis­tributed as part of the l3­pack­ages bun­dle.
