configure.am:
* Explicitly disallow --enable-rebuild-docs when builddir != srcdir, per
what you said about needing to build docs with an in-source build
doc/Makefile.am:
* Ensure that xmlversion.h is in the source tree before running
apibuild.py, to avoid generating an incomplete libxml2-api.xml
* Update the .PHONY target (forgot to do this earlier)
doc/devhelp/Makefile.am:
* Wrap the doc-generating rule in an "if REBUILD_DOCS" conditional so it
doesn't cause trouble for regular users
* Added a handy-dandy "rebuild" target
doc/examples/index.py:
* NOTE: You need to run this script to regenerate the files it creates,
and then commit the newly-updated files! The generated files currently
in git master (e.g. doc/examples/Makefile.am) are out of date even
before this patch!
* index.html really needs to be in EXTRA_DIST
* Wrap the doc-generating rules in an "if REBUILD_DOCS" conditional,
because they shouldn't be active otherwise
