CLI parser for jinja2 template files using jinjava (and so only supports features supported by jinjava).
$ java -jar j2s-cli-v0.1.jar
Usage: j2s-cli [options]
-i, --input <file> input file
-o, --output <file> optional output file - do not set to use stdout
Variables in the jinja2 template will be read from the environment and can also be passed as:
