    - (re-)create message file per object?
        - yes, but do not necessarily save in object space
        - save $anywhere

    - object_run
        - current notifications are imported into a file available at $__messages_in
        - after object run, everything that has been written to $__messages_out is merged into the $__messages file

        - functions:
            self.explorer.run_global_explorers(self.local.global_explorer_out_path)
            self.manifest.run_initial_manifest(self.local.initial_manifest)
                self.local.run_script(initial_manifest, env=self.env_initial_manifest(initial_manifest))
            self.explorer.run_type_explorers(cdist_object)
            self.manifest.run_type_manifest(cdist_object)
                self.local.run_script(type_manifest, env=self.env_type_manifest(cdist_object))
            self.code.run_gencode_local(cdist_object)
                self.local.run_script(script, env=env, return_output=True)
            self.code.run_gencode_remote(cdist_object)
                self.local.run_script(script, env=env, return_output=True)


    - message support in ...
        - initialmanifest - yes
        - explorer - no
        - only locally - yes
        
    - how to use notification / messaging in cdist
        - can be used in all local scripts:
            - initial manifest
            - type manifest
            - type gencode-*
        - order of object exeution is random or as you requested using require=""

    - example use:

__file/gencode-local:
         if [ "$local_cksum" != "$remote_cksum" ]; then
            echo "$__remote_copy" "$source" "${__target_host}:${destination}"
            echo "copy" >> "$__messages_out"
         fi
 
__nginx/manifest:
    __file /etc/nginx/sites-enabled/myfile --source "$__type/files/nginx-config"

__nginx/gencode-remote:
    if grep -q "__file/etc/nginx/sites-enabled/myfile:copy" "$__messages_in"; then
        echo /etc/init.d/nginx restart
    fi
