Rather than rendering a different version of the release notes for
every architecture, we now produce a single release notes document
that covers all architectures.
This change makes document maintenence easier (because there is no
longer a need to support each architecture specifically in the
src/release/doc/ and www/ build infrastructures). It's also
easier to read because there is now exactly one release notes document,
and readers can see changes that affected various subsets of
architectures.
Discussed on: -doc@
build.
This will give ia64 folks the chance to help flesh these out, and
also ensure that (when the time comes) ia64 releases with documentation
won't fall over due to missing RELNOTESng files.
o Define a RELN_ROOT variable which points to the root of the relnotes
tree (i.e., src/release/doc).
o By default, define DOC_PREFIX in terms of RELN_ROOT; this gives a
bigger chance of finding the doc/ tree without help in the form of
setting DOC_PREFIX on the command line.
o Respect DOCDIR; `make install` works now.
