/**
 * This class exports the "file-stream-internal" module, which is the Java "half" of the "java-file"
 * module. It actually just exports two "classes" (aka constructor functions) which
 * are implemented in different files.
 *
 * This class will be loaded as part of "require" if (and only if) it has an entry in the file
 * "META-INF/services/io.apigee.trireme.core.NodeModule," which in this sample it does.
