alnumsec – Alphanumeric section numbering

This pack­age al­lows you to use al­phanu­meric sec­tion num­ber­ing, for in­stance “A. In­tro­duc­tion … III. In­ter­na­tional Law”. Its out­put is sim­i­lar to al­phanum, but you can use the stan­dard LaTeX sec­tion­ing com­mands, so that it is pos­si­ble to switch num­ber­ing schemes eas­ily. Greek let­ters, dou­ble let­ters (bb) and dif­fer­ent de­lim­iters around them are sup­ported.
