$CASE/gen/ver_13/aareadme_genv13 -RJL050718

Update RJL070201: 
chgen run command has this option: -DNEW_VERSION
which controls whether version byte of pfkeys is updated
on request. I deprecate version numbers - they will
be removed and replaced by larger row# and/or namespace bits 
(24 or 20 and 0 or 4 resp).
They are ignored #ifndef NEW_VERSION (see pr_load/dump).

NB: chgen Makefiles optionally have -DNEW_VERSION.
bde/pr_util_*log files do not have -DNEW_VERSION during make, 
nor do they have #define NEW_VERSION inside.

Rev. 070218: 
BUT: There are also some #ifndef NEW_VERSION ... #endif code blocks.
In load_data:
---------
#ifndef NEW_VERSION
        if (((char) hcg_version) !=
            hcg_view_list.view_list[hcg_view_idx].version_list[hcg_tbl_idx])
        {
            rowsNotInView++;
            hcg_read_next();
            continue;
        }
#endif
------------ 



-------------------------

Update RJL 050916: 
I changed options -ansi and -nobp into defaults;
the (deprecated) non-default options now are -noansi and -bp.

-----------------------

Tonight I did cvs release chgen and rm -r chgen,
to prepare for a new checkout of genv13 sources.

This version was checked in on 050717  from $RB = 
    $CASE/04f522/lechner/genv13SBLMMM_Final/chgen
with platform-specific makefiles and it builds and 
generates the checked-in pr_*.c amd m*.h files  
on both Linux and alpha platforms, using the 
[default] command options
	chgen13 [-ansi -nobp] metaschema.sch.
