NITRO Code Snippets

This page contains snippets of code, and sometimes mini-tutorials showing how to use portions of the NITRO API. The snippets are not necessarily full programs, but they are chunks of code that developers can use to learn the basic functionality. The page is divided into sections for each released binding (currently C and Java) and for each version of the library.
