		Release notes-outer_brev 2.0a 

	outer_brev requires outer_utils.c and outer.h.  It has always
required path_info_routines.c & .h.  Previously (some version before version
1.3) these files were included as source.  In this release, they are included
as a .tar file.  If you wish to use them from the same directory as outer,
please untar.  If you wish to put the path_info routines elsewhere, we 
suggest NOT untarring in the outer directory to be sure that you're getting 
the software from the your intended directories.

	outer_brev v 2 addresses a problem that arose with the .brev
feature.  Briefly, .brev implementations prior to v 2 would stop calling
inner's ioreadrec_ entry when outer no longer wanted any data, and then
start calling again when it wanted new data.  Depending on how inner
was supplying the data, this could cause problems.
        To address this, outer_brev v 2 will call inner until inner
supplies EOF, whether or not outer intends to display the data.  This means
that, in a .brev situation, outer_brev v 2 will call inner many more times
than outer_brev 1.5 did.
	Details (including how to return to 1.5 behavior) are available in 
the outer_brev.doc file mentioned below.

	The comments at the top of outer_brev.c are the most complete
documentation of the changes in this release.  The outer_brev_revision.doc
file contains older source comments removed from outer_brev.c for
convenience.  The outer_brev_switches.doc file summarizes available 
compilation switches.  Most compilation options are also available as 
environment variables at runtime.  The outer_brev.doc file is a discussion 
of the ".brev" data listing feature.

	outer_brev requires file error_exit_defn.h to be in
the include path of the various compilation commands used to compile outer.
Installation of the latest path_info_routines package (path_info12a.tar;
included in outer20a.tar) is one way to take care of this.

	The comments in the first paragraph, above, relating to
path_info_routines.c are also relevant to outer_utils.c.
