(** Coq compiler : coqc *)
(** For improving portability, coqc is now an OCaml program instead
of a shell script. We use as much as possible the Sys and Filename
module for better portability, but the Unix module is still used
here and there (with explicitly qualified function names Unix.foo).
We process here the commmand line to extract names of files to compile,
then we compile them one by one while passing by the rest of the command
line to a process running "coqtop -batch -compile <file>".
