If you comment out lines pushing changes to remote repository (line 125), clean-up of working directory (line 64), and two REST requests updating JIRA ticket (lines 182-205); you can perform a dry run to make sure the script works well.

Comments welcome. Improvement ideas?

I have just pushed little more changes (validations, Git account configuration). Please let me know what you think and if direction is correct.

Thanks for this @lukasz-antoniak. I really would have hoped you didn't start from scratch but did small modifications on an existing merge script such as the one from Spark as that would give us the benefit of being used and tested in large scale in multiple projects for a little while. I would like to suggest you take a quick look at the merge-script from Spark and suggest what we should do as next steps: update this one versus adopting an existing one with modifications to any specific use case we might have.
