Seems reasonable, though leaving the MODULE_* metadata commented out at the end seems odd. I'd suggest using the DESCRIPTION to update the comment at the top (which is actually outdated and needs s/classic/hierarchical/), dropping the MODULE_LICENSE (redundant with the license header), and changing "MODULE_AUTHOR" into an "Author:" under the copyright.
