pzc­cal – Zapf Chancery as cal­li­graphic math al­pha­bet

The pzc­cal pack­age en­ables for­mat­ting Greek and Latin let­ters as sym­bols for vec­tors, ma­tri­ces, and ten­sors in the type­faces rec­om­mended for sci­en­tific pa­pers by the In­ter­na­tional Stan­dard ISO 31.
The au­thor has now de­clared the pack­age ob­so­lete, since he be­lieves that the ur­wchan­cal pack­age does the job bet­ter.
