+""" 
+ This tool builds a release from the a given elasticsearch branch.
+ In order to execute it go in the top level directory and run:
+   $ python3 dev_tools/build_release.py --branch 0.90 --publish --remote origin
+
+ By default this script runs in 'dry' mode which essentially simulates a release. If the
+ '--publish' option is set the actual release is done. The script takes over almost all
+ steps necessary for a release from a high level point of view it does the following things:
+
+  - run prerequisit checks ie. check for Java 1.6 being presend or S3 credentials available as env variables
+  - detect the version to release from the specified branch (--branch) or the current branch
+  - creates a release branch & updates pom.xml and Version.java to point to a release version rather than a snapshot
+  - builds the artifacts and runs smoke-tests on the build zip & tar.gz files
+  - commits the new version and merges the release branch into the source branch
+  - creates a tag and pushes the commit to the specified origin (--remote)
+  - publishes the releases to sonar-type and S3
+
+Once it's done it will print all the remaining steps.
