Attention : ce fichier {\tt test\_etex.tex} produit une sortie quasiment identique au fichier {\tt test\_latex.tex}, mais il doit se lancer avec Plain $\varepsilon$-\TeX. Pour des raison d'encodage, contrairement au fichier {\tt test\_latex.tex}, les arguments des macros présentées ici ne contiennent pas de lettres accentuées.\vskip2em

Toutes les situations ne sont pas envisagées, mais au moins un grand nombre ! Les macros sont examinées dans l'ordre logique du code.

Lorsque le résultat contient des espaces ou peut conduire à des doutes, il sera entouré de ''\delimiteur``, étant entendu que ''\delimiteur\delimiteur`` est une chaine vide.\vskip2em
