The following example demonstrates how Iffe works for the developer. In this example, it simply creates some variables in C++ which are then modified by JS whilst being output using the JS alert box and the C++ cout.
You can download an early version of the software here.
tar -xf em_iffe-0.1.1.tar.gz cd em_iffe // Change the em++ path in Makefile make
Then simply open the newly generated index.html in a web browser.
