# We avoid adding all the dependencies except in maintainer mode.  This is
# because the automake team feels that you should not require the user
# to have makeinfo and friends installed just to build the package.
# This seems reasonable.  Because of that, the documentation must be
# built in the source directory so it can be found when creating a distfile
# and this means you can't build outside the source tree with a read-only
# source.  So, ignore the dependencies unless we're in maintainer mode
# but be sure and put the generated files in the distfile via EXTRA_DIST
# and dist_pkgdata_DATA.  Also this helps us avoid problem with users
# having various out of date versions of the texinfo package installed
# which can have all sorts of issues.
