\section{Library initialization}

Before you can start using the facilities of the [[cfg]] library,
the library must initialize some parts of itself.  In SUIF, this is
performed by defining an [[init_]]\emph{libname} routine.

<<cfg library initialization>>=
extern "C" void init_cfg(SuifEnv* suif_env);
@

The following string keys the annotation that connects a label to the
corresponding CFG node.

<<cfg string constants>>=
extern IdString k_cfg_node;
@

The [[cfg]] library initialization header has the following layout:

<<init.h>>=
/* file "cfg/init.h" */
