+/*++
+/* NAME
+/* mkmap_cdb 3
+/* SUMMARY
+/* create or open database, CDB style
+/* SYNOPSIS
+/* #include <mkmap.h>
+/*
+/* MKMAP *mkmap_cdb_open(path)
+/* const char *path;
+/*
+/* DESCRIPTION
+/* This module implements support for creating DJB's CDB "constant
+/* databases".
+/*
+/* mkmap_cdb_open() take a file name, append the ".cdb.tmp" suffix,
+/* create the named DB database. On close, this file renamed to
+/* file name with ".cdb" suffix appended (without ".tmp" part).
+/* This routine is a CDB-specific helper for the more
+/* general mkmap_open() interface.
+/*
+/* All errors are fatal.
+/* SEE ALSO
+/* dict_cdb(3), CDB dictionary interface.
+/* LICENSE
