How to make a release

Preparation

Change the artifact ID in pom.xml to today's date, e.g.:
```
2016.6.6-SNAPSHOT
```

Update the version, date and URL in Description.props to reflect new version, e.g.:

Version=2016.6.6
Date=2016-06-06
PackageURL=https://github.com/fracpete/multisearch-weka-package/releases/download/v2016.6.6/multisearch-2016.6.6.zip

Run the following command to generate the package archive for version 2016.6.6:
```
ant -f build_package.xml -Dpackage=multisearch-2016.6.6 clean make_package
```
create a release tag on github (v2016.6.6)
add release notes
upload package archive from dist
add link to this zip file in the Releases section of the README.md file
notify Mark Hall about new release

Run the following command to deploy the artifact:

mvn release:clean release:prepare release:perform

skip tests with:

export MAVEN_OPTS="$MAVEN_OPTS -DskipTests=true"

After successful deployment, push the changes out:
```
git push
```
After the artifacts show up on central, update the artifact version used in the dependency fragment of the README.md file
