sube­q­nar­ray – Equa­tion ar­ray with sub num­ber­ing

This pack­age de­fines the sube­q­nar­ray and sube­q­nar­ray* en­vi­ron­ments, which be­have like the cor­re­spond­ing eq­nar­ray and eq­nar­ray* en­vi­ron­ments, ex­cept that the in­di­vid­ual lines are num­bered like 1a, 1b, 1c, etc. To re­fer to these num­bers an ex­tra la­bel com­mand \sla­bel is pro­vided.
Users are urged to con­sider the align­ment ca­pa­bil­i­ties of the ams­math bun­dle, which pro­duce bet­ter re­sults than eq­nar­ray-re­lated macros.
