cmd­track – Check used com­mands

The pack­age keeps track of whether a com­mand de­fined in a doc­u­ment pream­ble is ac­tu­ally used some­where in the doc­u­ment. After the pack­age is loaded in the pream­ble of a doc­u­ment, all \new­com­mand (and sim­i­lar com­mand def­i­ni­tions) be­tween that point and the be­gin­ning of the doc­u­ment will be marked for log­ging. At the end of the doc­u­ment a re­port of com­mand us­age will be printed in the TeX log, for ex­am­ple: – “mdash was used on line 25”; – “ndash was never used”.
