# libdom for MontaukOS
#
# Upstream: https://github.com/netsurf-browser/libdom (official mirror of
# git.netsurf-browser.org; submodule at upstream/, pinned, no local patches).
#
# DOM implementation. Depends on libparserutils, libwapcaplet and libhubbub,
# all of which must already be in the ports sysroot -- libdom finds the latter
# two through pkg-config (REQUIRED_PKGS), which is why the library ports
# publish .pc files into sysroot/lib/pkgconfig.
#
# Bindings come from libdom's checked-in Makefile.config, which defaults the
# expat AND hubbub bindings to yes. Those are plain `:=` assignments, so
# passing the variables on the sub-make command line overrides them without
# patching upstream or dropping a Makefile.config.override into the submodule:
#   WITH_HUBBUB_BINDING=yes   how NetSurf feeds HTML into the DOM; required.
#   WITH_EXPAT_BINDING=no     defaults to YES upstream and must be turned off
#                             -- it needs <expat.h>, which MontaukOS has no
#                             port of, and NetSurf does not use it.
#   WITH_LIBXML_BINDING       already no in their config; set explicitly so a
#                             future upstream flip cannot surprise us.
#
# Needs perl on the BUILD host.
