[stringtemplate-interest] Command line app for printing templated text?

[Nathan Gagnon]

Does anyone know of a simple command line app that simply prints
generated text from stringtemplates?  Something that takes in the .stg
file, the name of the target template, and your string arguments for
it.

Basically what I'm looking for is something I can call like:
> StringTemplateApp.exe MyTemplates.stg TemplateName "arg1" "arg2" ...

I know the app would be easy to write, but my hunch is that its
already been done, and I'd like to reuse if possible.

Thanks!
Nathan
