Using the module as a plugin

Hi

How could I use the module as a plugin. There was no problem with j10 but I cant do that with j15.

PS : I have tried to insert my feeds with mosmodule and sourcerer plugins but it does not work. The include statement is not executed. It appears in source code when my page is loaded.

{source}
<jdoc:include type="modules" name="rss" style="raw" />
{/source}

{mosmodule phpinc=./rss/widget_rss.php}
