At the moment it provides a module wrapping the C++ std::streambuf class
and wrappers for constructors instanciating (subclasses of) this class.
(File, Net) - additionaly the stream module always provides - stdout,
stdin, stderr objects

The file module test:
ejs.ModuleLoader.load("File");
if (!File.mode.read)
	throw new Error("failed");
stream=File.open("Makefile",File.mode.read);
if ((s=stream.read(10))!="# Makefile")
	throw new Error("failed: \""+s+"\"");
stream=File.read("Makefile");
if ((s=stream.read(10))!="# Makefile")
	throw new Error("failed: \""+s+"\"");
fname="delme-filetest-346x63hg3";
stream=File.write(fname);
stream.write("Hello World");
stream.sync();
stream=File.read(fname);
s=stream.read(11);
if (s!="Hello World")
	throw new Error("failed: \""+s+"\"");

Note:
- doesn't support unicode yet
- especially the net module is quite ugly

The examples encode the resources into the source for two reasons:
The security modell of ejs is simplistic:
- it has an untrusted mode (others would probably call it a restricted
shell), which if entered doesn't allow much (no new network connections,
no filesystem access, ...)
- to have the example completely in one file
