emarks – Named mark registers with e-TeX

E-TeX pro­vides 32 768 mark reg­is­ters; us­ing this fa­cil­ity is far more com­fort­able than LaTeX tricks with \markright, \mark­both, \left­mark and \right­mark.
The pack­age pro­vides two com­mands for mark­ing: \mark­s­the and \mark­s­thecs, which have * forms which dis­able ex­pan­sion; new mark reg­is­ters are al­lo­cated as needed. Syn­tax is closely mod­elled on the \marks prim­i­tive.
Four com­mands are pro­vided for re­triev­ing the marks reg­is­ters’ con­tent: \the­first­marks, \the­bot­marks, thetop­marks and \get­the­marks; and the com­mand \if­mark­se­qual is avail­able for com­par­ing the con­tent of marks reg­is­ters.
The pack­age re­quires an e-TeX-en­abled en­gine, and the etex pack­age.
