# FreeDink consists of multiple parts:
# * The engine – this is an open source reimplementation of the game Dink Smallwood.
# * The editor – it is part of the enigne.
# * The game data – telling the same story as the original game.
#   If you have a copy of the original game, you can also use the original files instead.
# * The mod manager DFArc – optional, to use modifications, such as extra stories.

# The mod manager DFArc can be started by right-clicking on the FreeDink application launcher.

# For the game to play midi files, one needs to install either timidity++ or fluidsynth and a soundfont.

# In case of timidity:
# - install timidity++
# - install a soundfont
# - configure /etc/timidity/timidity.cfg

# Using fluidsynth (current solution):
# - install fluidsynth
# - install a soundfont
# - set environment variable SDL_SOUNDFONTS
#   Examples:
#   SDL_SOUNDFONTS=/usr/share/soundfonts/FluidR3_GM.sf2
#   SDL_SOUNDFONTS=/usr/share/soundfonts/FluidR3_GM.sf2:/usr/share/soundfonts/FluidR3_GS.sf2
#   (This is done by the sound.patch)

# Using timidity is a better solution, because
# - one of the files cannot be played with fluidsynth.
# - sound is played quieter with fluidsynth.
#
# Debian Buster uses timidity, but the configuration differs a lot.
# The way it's explained in the Arch wiki and example config works for
# using timidity standalone, but not for using it with freedink.
