It is also possible to invoke multiple transformations with a single command

If no output directory is defined, all output is written to stdout.

> [freemarker-generator] Support an output "generation" mode
> ----------------------------------------------------------
>
> Key: FREEMARKER-188
> URL: https://issues.apache.org/jira/browse/FREEMARKER-188
> Project: Apache Freemarker
> Issue Type: Improvement
> Reporter: Siegfried Goeschl
> Assignee: Siegfried Goeschl
> Priority: Major
>
> The current "freemarker-generator" implementation supports only
> "aggregation" of multiple data source, e.g. one template takes 0..N data
> sources to generate a template output (stdout or file)
> *1 template + 0..N data sources -> 1 template output*
> We need to provide a "generation" type of transformation as well in order to
> provide
> *1 template + 1..N data sources -> 1..N template outputs*
> Topics to be resolved
> * We need something like an "Output Mapper" to determine the final path
> and/or name of the generated output file
> * We need a way to distinguish between "generate" and "aggregate", e.g. using
> a command line parameter
> ** "--output-mode=generate|aggregate" or
> ** "--seed=template|datasource"
> * We need to support multiple transformations on the command line (mostly
> because JVM is slow to start)
