GlueGen is a tool which automatically generates the Java and JNI code
necessary to call C libraries. It reads as input ANSI C header files and
separate configuration files which provide control over many aspects of
the glue code generation. GlueGen uses a complete ANSI C parser and
an internal representation (IR) capable of representing all C types
to represent the APIs for which it generates interfaces. It has
the ability to perform significant transformations on the IR before
glue code emission. GlueGen is currently powerful enough to bind even
low-level APIs such as the Java Native Interface (JNI) and
the AWT Native Interface (JAWT) back up to the Java programming language.
