/* 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)

/* void cleanup_rewrite_tree(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.
