[stringtemplate-interest] [ST4 Beta-4] Retrieving version information

[Udo Borkowski]

Hi Ter,

I agree this will only work if the version information (text and/or boolean flag) is really in sync with the version control system (i.e. requires automated solution). Not sure how hard this is to implement.

Regarding the test for the version: I haven't thought of this yet, but it would definitely be useful.
