This is the top-level directory for RELNOTESng, a re-write of
FreeBSD's *.TXT documentation files.  They have been converted to
DocBook, and versions of the documents can be now be built for various
supported architectures.  The output files can be rendered in any
format supported by the FreeBSD Documentation Project (for example,
ASCII text, PDF, PS, HTML).

RELNOTESng requires that the FreeBSD doc/ sources are installed; it
leverages off of much of the DocProj build infrastructure, including
DocBook extensions and stylesheets.  If the doc/ sources are not
installed in /usr/src, their location should be specified with the
DOC_PREFIX Makefile variable.  RELNOTESng also requires the DocProj
build tools, which can easily be installed with the textproc/docproj
port in the Ports Collection.

share/sgml/*.dsl
	Architecture-dependent stylesheets.  These stylesheets support
	the arch= attribute on (all?) DocBook elements.  Currently-
	supported values are:  i386, alpha.
share/sgml/release.ent
	Release information.  Need to update the entry definitions in
	this file when rolling new revisions; these should take effect
	in all documents.

*/relnotes/common/
	Directory for multi-architecture release notes files.
*/relnotes/*/
	Directories for architecture-specific release notes files.

*/hardware/common/
	Directory for multi-architecture hardware notes files.
*/hardware/*/
	Directories for architecture-specific hardware notes files.

*/installation/common/
	Directory for multi-architecture installation notes files.
	Note that the FreeBSD DocProj build infrastructure does
	not handle documents (or subdirectories) named "install" 
	well, so we call our document "installation" and do
	a hack when it gets installed into a distribution to fix
	this up.
*/installation/*/
	Directories for architecture-specific release notes files.

*/errata/
	Directory for errata document.

*/readme/
	Directory for (introductory) document.

All definition of the "current" version of FreeBSD is contained in the
share/sgml/release.ent file; release engineers should peruse the
contents of this file carefully when doing version number bumps.

When creating content for the architecture-dependent files, authors
should use the arch= attribute to elements that are specific to a
particular machine architecture.  The value of this attribute should
be a single word that indicates for which architecture the current
element will be included.  For example:

	<para arch="alpha">Alpha-specific text</para>

The currently-supported architectures are i386 and alpha.  As of this
writing there is no mechanism for supporting multiple architectures
(i.e. arch="alpha,ia64"), but with some work in the stylesheets this
should be possible.

When creating a translation, make a new directory under this
directory with a language code (paralleling the DocProj directory
structure).

RELNOTESng is supported in the FreeBSD release-build process.  For
now, the building of RELNOTESng is enabled by RELNOTESNG=YES when
building a release.  Note that setting RELNOTESng requires that both
NODOC and NOPORTS *not* be set, as RELNOTESng require parts of
both.  Eventually, RELNOTESNG will be made the default.

Release builders can set which language gets built with the 
RELNOTESNG_LANG variable; note that this is different from the 
DOC_LANG variable because (at least intially) most languages
will have localized DocProj files but not localized release notes.
The default language, if none is specified, is en_US.ISO_8859-1.
