[1] Pre-built documentation is present in this tarball. make will detect that documentation already exists in the distribution if make clean was not run, and will not require the xmlto-0.0.29 dependency. However, running make clean will result in the pre-built documentation being deleted, thus requiring xmlto to build the documentation if make is run afterwards.
