   3 #### make-dist: create an Emacs distribution tar file from the current
   4 #### source tree.  This basically creates a duplicate directory
   5 #### structure, and then hard links into it only those files that should
   6 #### be distributed.  This means that if you add a file with an odd name,
   7 #### you should make sure that this script will include it.
