(* Afin de rendre Coq plus portable, ce programme Caml remplace le script
coqc.
Ici, on trie la ligne de commande pour en extraire les fichiers à compiler,

à un process "coqtop -batch -load-vernac-source <fichier>".
On essaye au maximum d'utiliser les modules Sys et Filename pour que la
portabilité soit maximale, mais il reste encore des appels à des fonctions
du module Unix. Ceux-ci sont préfixés par "Unix."
