-# NAME
-#      mkcsrc - generate a new c_src directory from a current nitc bootstrap
-# SYNOPSIS
-#      ./mkcsrc [number]
-# DESCRIPTION
-#      transform a bootstrap result (generated by the nc tool) into a new
-#      c_src in the current directory (previous one will be errased).
-#      One c_src generated, you can replace the old one in the root.
-#      Before commiting, do not forget to:
-#       * verify any regression
-#       * add/remove files in c_src
-# OPTION
-#      number is the bootstrap level (prefix) to use. It correspond to the nc
-#      level.  By default, the lastest generated nitc is used
-
-# prefix
-p=$1
