[syslog-ng] Injecting environment variables?

[Balazs Scheidler]

It came in with blocks and scl support. So if your version has support for
the system driver it will support this as well. My memories are vague with
3.2.

Environment variables are resolved at parsing time and should work like
this:

Template("template ‘envvar‘")

It works as if the environment variable was right there in the config file.
