dox – Extend the doc package

The doc pack­age pro­vides LaTeX de­vel­op­ers with means to de­scribe the us­age and the def­i­ni­tion of new macros and en­vi­ron­ments. How­ever, there is no sim­ple way to ex­tend this func­tion­al­ity to other items (op­tions or coun­ters, for in­stance). The DoX pack­age is de­signed to cir­cum­vent this lim­i­ta­tion.
