i18n Maven Plugin to create Sling mix:language content structure

it is very tedious to write sling i18n resource manually in this very verbose format
http://sling.apache.org/site/internationalization-support.html#InternationalizationSupport-SampleResources

instead, the goal it to write it in an very easy an compact format e.g.

• java properties i18n file

• json file (allows nesting for building key hierarchies)

• xml file (allows nesting for building key hierarchies)

all those input files are transformed during maven build to the sling destintation format in either JCR content JSON or XML format.
