-/*! \file
- *
- * \brief A program to read in the /tmp/refs file generated
- * by astobj2 code when the REF_DEBUG macro is defined.
- * It will read in the file line by line, and
- * sort the data out by object, and check to see
- * if the refcounts balance to zero, and the object
- * was destroyed just once. Any problems that are
- * found are reported to stdout and the objects
- * ref count history is printed out. If all is well,
- * this program reads in the /tmp/refs file and
- * generates no output. No news is good news.
- * The contents of the /tmp/refs file looks like this:
- * \verbatim
- * 0x84fd718 -1 astobj2.c:926:cd_cb_debug (deref object via container destroy) [@1]
- * 0x84fd718 =1 chan_sip.c:19760:build_user (allocate a user struct)
- * 0x84fd718 +1 chan_sip.c:21558:reload_config (link user into users table) [@1]
- * 0x84fd718 -1 chan_sip.c:2376:unref_user (Unref the result of build_user. Now, the table link is the only one left.) [@2]
- * 0x84fd718 **call destructor** astobj2.c:926:cd_cb_debug (deref object via container destroy)
- * \endverbatim
