Can there be other stuff on the line after #!KAMAILIO?

For example emacs can be told about the major mode used in the file by
checking if first non-blank line contains  -*-<something>-*-.

So I would like the definition go like this:

`--cfg-print` works if the main configuration file starts with

#!KAMAILIO
