A simple tool to syncronize two directories with low latency.

The initial version never runs `rsync --delete ...` as-is which causes
this sync to usually not be complete. However, while the sync is active
the deletes will be syncronized for all events that inotify-tools is
able to detect.

In practise, the current version of this tool may end up leaving some
files not deleted in the target. If you feel brave, you can add `--delete`
to every `rsync` in the script.

Usage:

    rsync-continuous my/directory/to/sync example.com:path/to/target

Will sync all files from directory `my/directory/to/sync` to remote
server "example.com" using rsync over ssh to remote directory `path/to/target`.

I created this tool to keep git repo and source files on local machine and
automatically syncronize all files (including the git repo) to remote machine
as soon as I modify any file. I previously used to use `sshfs` to mount
remote directory locally but even with high bandwidth connection it's getting
too slow for my liking. I'm used to get immediate response from git and
with sshfs even `git status` takes a lot of time when the git repo I'm working
with is big enough. In practice, I once do initial full rsync from remote
working directory to local machine using

    rsync -av --delete example.com:path/to/target/ my/directory/to/sync

and then start the above rsync-continuous and keep hacking with the local
source. Note that you don't need to add a slash to the end of source directory
like with rsync.
