### make-dist: create an Emacs distribution tar file from current srcdir
## Copyright (C) 1995, 1997-1998, 2000-2022 Free Software Foundation,

### Commentary:
## 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.
### Code:
progname="$0"
### Exit if a command fails.
#set -e
### Print out each line we read, for debugging's sake.
