mail­ing – Macros for mail merg­ing

This pack­age is for use when send­ing a large num­ber of let­ters, all with the same body text. The pack­age‘s \ad­dress­file com­mand is used to spec­ify who the let­ter is to be sent to; the body of the \mail­ing­text com­mand spec­i­fies the text of the let­ters, pos­si­bly us­ing macros de­fined in the \ad­dress­file.
