/* NAME
/* dict_debug 3
/* SUMMARY
/* dictionary manager, logging proxy
/* SYNOPSIS
/* #include <dict_debug.h>
/*
/* DICT *dict_debug_open(name, open_flags, dict_flags);
/* const char *name;
/* int open_flags;
/* int dict_flags;
/* DESCRIPTION
/* dict_debug_open() encapsulates the named dictionary object and
/* returns a proxy object that logs all access to the encapsulated
/* object.
/*
/* If the encapsulated dictionary is not already registered, it is
/* opened with a call to dict_open(\fIname\fR, \fIopen_flags\fR,
/* \fIdict_flags\fR) before registering it.
/* DIAGNOSTICS
/* Fatal errors: out of memory.
