# amazon-ebs: 2. keep the local version currently installed
# amazon-ebs: 3. show the differences between the versions
# amazon-ebs: 4. show a side-by-side difference between the versions
# amazon-ebs: 5. show a 3-way difference between available versions
# amazon-ebs: 6. do a 3-way merge between available versions (experimental)
# amazon-ebs: 7. start a new shell to examine the situation
