4# Use this script to recreate the 'dist' subdirectory from a newly released
5# distfile.  The script takes care of unpacking the distfile, removing any
6# files that are not relevant to NetBSD and checking if there are any new
7# files in the new release that need to be addressed.

9# See the README file for general instructions.
