/* NAME
/* cleanup_rewrite 3
/* SUMMARY
/* address canonicalization
/* SYNOPSIS
/* #include <cleanup.h>
/*
/* void cleanup_rewrite_external(result, addr)
/* VSTRING *result;
/* const char *addr;
/*
/* void cleanup_rewrite_internal(result, addr)
/* VSTRING *result;
/* const char *addr;
/*
/* void cleanup_rewrite_tree(tree)
/* TOK822 *tree;
/* DESCRIPTION
/* This module rewrites addresses to canonical form, adding missing
/* domains and stripping source routes etc., and performs
/* \fIcanonical\fR map lookups to map addresses to official form.
/*
/* cleanup_rewrite_init() performs one-time initialization.
/*
/* cleanup_rewrite_external() rewrites the external (quoted) string
/* form of an address.
/*
/* cleanup_rewrite_internal() is a wrapper around the
/* cleanup_rewrite_external() routine that transforms from
/* internal (quoted) string form to external form and back.
/*
/* cleanup_rewrite_tree() is a wrapper around the
/* cleanup_rewrite_external() routine that transforms from
/* internal parse tree form to external form and back.
/* DIAGNOSTICS
/* LICENSE
/* .ad
