+tsort-about = Tri topologique des chaînes présentes dans FILE.
+  Les chaînes sont définies comme toute séquence de jetons séparés par des espaces (tabulation, espace ou saut de ligne), ordonnées selon les dépendances dans un graphe orienté acyclique (DAG).
+  Utile pour la planification et la détermination de l'ordre d'exécution.
+  Si FILE n'est pas fourni, l'entrée standard (stdin) est utilisée.
