This is probably a good place to discuss a guideline, and we can
either add this to the wiki later, or include such a guideline
document with the Waf we ship.

- Bundling: assuming new Waf releases are backward-compatible, we
should probably default to recommending the use of system Waf for
Fedora packages, for the same reason that this is recommended in
general -- there might be bugfixes, etc. that were not available when
upstream did the packaging of the source.

- compiler flags, logs: the following options are relevant

"""
CFLAGS

    Selects compilation options for when the C compiler is used, e.g. "-Wall".

CXXFLAGS

    Selects compilation options for when the C++ compiler is used,
e.g. "-Wall".
"""

Seems like CFLAGS="$RPM_BUILD_OPTS -Werror" should do the trick.

- parallel build:
"""
JOBS

    The amount of parallel jobs when building targets, if no --jobs
option is given.
"""

waf takes the short option -j as well, so this is almost identical to
using make:
waf build %{?_smp_mflags}

It looks like there's already a page for using cmake:
http://fedoraproject.org/wiki/Packaging:Cmake so the Waf page should
eventually end up there, after going through PackagingDraft.
