| Grails 2.x and below has an `application.properties` that can be utilized to store commit properties. |
| This is the same place that Grails used to store its application name and version. |
| |
| In this example some mechanism needs to be in place to append/update the commit info to the `application.properties` |
| It could be the build system that appends git commit info as a build step before producing a war. |
| |
| After the commit info is added to `application.properties` We can access that metadata in several ways: |
| |
| * GrailsApplication via `grailsApplication.metadata['git.sha']` |
| * Utilizing the taglib `<g:meta name='git.sha'/>` in a view. |
