At this early stage, I've just found that Waf doesn't provide any
built-in generic function to check a program version, so I'm writing a
function to provide this feature, and I have started writing a Waf tool
for Texinfo. The two tasks you could look at to begin are
- add attached wscript to top of the source directory, replace
hard-coded VERSION by some code that parses the VERSION file (Python std
lib has a module for parsing configuration files), and commit this
wscript to dev/waf branch;
- add configure (conf) function stub in wscript, that sets in Waf
environment the correct value of LILYPOND_BINARY, trying in the
following order:
1) get and check value LILYPOND_EXTERNAL_BINARY from system
environment
2) if GNUmakefile and config.make exist in the build tree (not in the
source tree!), and last line of config.log is "configure: exit 0", then
we can assume that the build tree has been configured for configuration
of LilyPond binary, so we set LILYPOND_BINARY to
"$(configure-builddir)/out/bin/lilypond --relocate"
3) use conf.check_program ('lilypond', var='LILYPOND_BINARY') to try
to find lilypond binary in PATH
Just look at the relevant parts of the Waf book and/or in demos in Waf
sources (installed in /usr/share/doc/waf-x.y.z/demos/ if waf is provided
by your distro).

Indeed. The web site would have certainly already been ready to be
released (including translations) if we had a more maintainable and
newcomers-friendly (if ever possible) build system.
Good luck,
