# this script assumes the following folder structure:
# This script lives at ./restart.sh

# There is the folder ./eathena, which holds the server sources
# There is the folder ./eathena-data which has content
# There is the folder ./tmwdata which contains the client data.

# Further on we need a tool called adler32 living at ./adler32 which 
# will sign the zip files (which will contain the updates for clientdata)
# These will start messing up the ./ folder here

# These zip files must be able to get from an updateserver, so either these zip files need to be moved
# to some folder which is properly setup with a http server, or the http server must service this folder.
