+(* This module is the heart of the library. It provides low level functions to
+   load, open and save modules. Modules are saved onto the disk with checksums
+   (obtained with the [Digest] module), which are checked at loading time to
+   prevent inconsistencies between files written at various dates. It also
+   provides a high level function [require] which corresponds to the 
+   vernacular command [Require]. *)
