+# 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
