Idea behind this tool is:

• sync actual state to VM via rsync
• create mutagen.io session aftewards for changes sync
• if folder to sync contains .mutagen file this command will take it as mutagen configuration file

• environment variable DOCKER_VM_USER must be set (e.g. VM default user "ubuntu")
• connection to VM for that ENVs must be via certificate (without password, test it with command shell ssh $DOCKER_VM_USER@$DOCKER_VM_HOST`)

Usage

$ cd <some folder to sync>

# create a sync session
$ ./bin/mutagen-sync

# drop sync session
$ ./bin/mutagen-sync d
