# How to use:
# 
# 0) Rename this to osync-srv, and place it in /etc/init.d.
# 1) Ensure that your config is located in /etc/osync, under some name with a
# .conf extension.
# 2) Ensure that osync.sh can be found in /usr/local/bin.                                                                                         
# 3) Ensure that you have rsync and inotify-tools installed.                                                                                      
# 4) Symlink this to a name with an extension equal to the basename of your                                                                       
# config file.
# 5) Add to the default runlevel under the symlinked name.                                                                                        
#                                                                                                                                                 
# Example:
#                                                                                                                                                 
# Suppose the config is located at /etc/osync/documents.conf. You then want to                                                                    
# symlink as follows:
#
# # ln -s /etc/init.d/osync-srv /etc/init.d/osync-srv.documents
# 
# Then you can start the service as normal:
#
# # rc-update add osync-srv.documents default
