# Program Name: Restore the restore 
# Purpose:      Take all the parts of a svnbackup.sh file and
#               try loading the svnadmin
# Usage:        1. Create the new repo path with svnadmin create
#               2. Set repo_name to the repo backup file names
#               3. Set restore_path to the new path to restore to
#               4. Run it ./svnbackup-restore.rb 
# Assumptions:  svnrestore-backup.rb is in the same dir as the svn dump files

# CHANGE PARAMETERS HERE
repo_name = 'myrepo'
restore_path = '/path/to/myrepo'

# Print out debugging?
DEBUG = true

# DON'T CHANGE BELOW

# Filename format is 'dumpfile-<svn reponame>-<start>-<end>.bzip2'
