# To approximate the DS builds A, B, C, ... run our configure like this
# configure --host=ds --disable-translation --disable-all-engines OPTIONS
# where OPTIONS is...
# build A: --enable-scumm
# build B: --enable-sky --enable-queen
# build C: --enable-agos
# build D: --enable-gob --enable-cine --enable-agi
# build E: --enable-saga --disable-mad
# build F: --enable-kyra --disable-mad
# build G: --enable-lure
# build H: --enable-parallaction
# build I: --enable-made --disable-mad
# build K: --enable-cruise --disable-mad
#
# However, this could be automated using a simple script, which generates
# subdirs for each build, and runs configure in those subdirs with the right
# parameters (all builds would still share the same set of source code files,
# thanks to our "out of tree" building support).
#
# This does not currently take care of some things:
# * It does not #define DS_BUILD_A etc. -- most uses of that should be
# eliminated, though. Only usage should be for selecting the default config
# file (and for that we should really rather allow overriding the value of
# DEFAULT_CONFIG_FILE).
# There are a few game specific hacks which are currently controlled by this,
# too; we need to investigate those.
# * It does not currently adjust the logo. Ideally, if we ever get real plugin
# support, that should be necessary anymore anyway.
# * No support for USE_DEBUGGER and USE_PROFILER yet. I envision that we would
# integrate them with the --enable-debug and --enable-profiling configure options,
# I simply haven't gotten around to do that yet.
# * ...
# Set location of ndsdir so that we can easily refer to files in it
ndsdir = backends/platform/ds
# Until we fix logo support, always use the A logo
LOGO = logoa.bmp
