### make-dist: create an Emacs distribution tar file from current srcdir

### 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.
#set -v
