clefval – Key/value support with a hash

This pack­age pro­vides only two macros viz. \TheKey and \TheValue to de­fine then use pairs of key/value and gives a sem­blance of a hash. Syn­tax: \TheKey{key}{value} to de­fine the value as­so­ci­ated to the key, does not pro­duce text; \TheValue{key} to re­turn the value linked to the key. Both ar­gu­ments of \TheKey are ‘mov­ing’ as LaTeX de­fines the term and we have some­times to pro­tect them.
