- the opam files in the branch where the script is launched should be correct
- if not, the second argument to the script should be a branch in which the opam files are correct

+# VERSION is the version number of the package to create, we expect
+#   there is a tag named mathcomp-$VERSION which archive we can
+#   download from github
+# BRANCH is the name of a branch where we can find accurate local opam
+#   files. Actually, this may only matter for the Coq version dependencies
+#   located in the ssreflect package.
