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