17.2. Register the Commenter
The SimpleCommenter implementation is registered with the IntelliJ Platform in plugin.xml using the lang.commenter extension point.
<extensions defaultExtensionNs="com.intellij">
<lang.commenter language="Simple" implementationClass="com.intellij.sdk.language.SimpleCommenter"/>
</extensions>
