### 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
