# This script does the converse of sdbackup by copying the saved files

|

# <backupdir> will be checked out on the local machine and the backups
|
|
# will be restored.

|
|
# Currently this script bails out if any of the files in <backupdir> are
|
|
# either already checked out or a different version than was backed up.
|
|
# Clever diffing and merging could be done here instead.
