Subject Re: How to disable some directives in Velocity Engine? How to avoid conflict of VTL comment and comments in shell script templates?

It was first that came to mind...
But usually users just using "copy-paste" - and don't bother with such things :)
Only alternative, I see now - use preprocessor and isolate blocks with VTL.

Does Velocity have some kind of "directive processor" like in other
template engines?
For example, "String Templates" or MS VS template engine?

I've tried to dig into code... So much hard-coded things, that it
remembered me programming classes 20 years ago - then we started to
learn C :)

Anyway, thanks for idea :)
