  22 ### Commentary:
  23
  24 ## This basically creates a duplicate directory structure, and then
  25 ## hard links into it only those files that should be distributed.
  26 ## This means that if you add a file with an odd name, you should make
  27 ## sure that this script will include it.

  29 ### Code:

  32
  33 ### Exit if a command fails.
  34 #set -e
  35
  36 ### Print out each line we read, for debugging's sake.
  37 #set -v
