# Description: Program to feed multicast/bt packets for clients to restore.
# What will be done in this program:
# 1. Image repository has to be mounted first.
# 2. Create a tarball about the image which contains all files in the image except file system image files.
# 3. Provide full command for client to run.
# For 2 and 3, the files will be put in httpd server.
# //NOTE// Bittorrent is still under development. Not enabled yet.
