Can be moved into exaudfclient/exa_vm_factory.cc

We already using streams for constructing sb, so we probably can also use cerr directly and don't need the string stream and the fprintf

We probably could move this also to cerr

We probably move this also to cerr

We are already using cerr, so we probably can use it here, too

Maybe we should move the ifdef into its own function, this would make this function easier to read

This introduces a bug: If there is no fourth CLI parameter, the environment variable SCRIPT_OPTIONS_PARSER_VERSION is never eveluated!

is_use_ctpg_parser is a strange name. Maybe just use_ctpg_parser?

scriptOptionsParserVersion is actually only relevant for Java

The Base class should be an abstract class and call here create_vm, however don't implement it. You mixed implementation of the client that supports all languages with the implementation of the abstract class. For the moment, we need the ExaudfclientBase as abstract class, ExaudfclientAllLangs, and we can add for each language its Exaudfclient{Lang} if we want to, however I would wait with later until we do the split into repos.
