#
# Usage
#

# Synopsis:
#
# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1
#
# (See below for the list of possible options.)
#
# Alternately, you can run make without the MANUAL_CONFIG part. It then
# generates Makefile.config, where you can customize all the options.
# However beware that for all subsequent calls the option values from
# Makefile.config take precedence to the commandline options.
#
# (That means that you probably want to either specify the options on command
# line together with MANUAL_CONFIG=1 or you want to specify no commandline
# options at all.)

# Targets:
#
# Defaults to building binary
# clean: remove intermediate build files
# mrproper: remove intermediate files and makefile configuration
# upgradeconf: add new options to old Makefile.config
# osx: OS X application
# release: used by OSX to make a dmg file ready to release

# Options:
#
# Summary of OS choice defines
# WIN32: building on Windows
# UNIX: building on *nix derivate (Linux, FreeBSD)
# OSX: building on Mac OS X
# MORPHOS: building on MorphOS
# BEOS: building on BeOS
# SUNOS: building on SunOS (Solaris)
#
# Summary of library choice defines
# WITH_ZLIB: savegames using zlib
# WITH_PNG: screenshots using PNG
# WITH_SDL: SDL video driver support
#
# Summary of other defines:
# MANUAL_CONFIG: do not use Makefile.config, config options set manually
# DEBUG: build in debug mode
# PROFILE: build in profile mode, disables -s and -fomit-frame-pointer
# DISPLAY_WARNINGS: when off, some errors are not displayed while compiling
# TRANSLATOR: build in translator mode (untranslated strings are prepended by
#             a <TODO> mark)
# RELEASE: this will be the released version number. It replaces all places
#          where it normally would print the revision number
# MIDI: if set, it will use it as custom path to midi player.
#  If unset, it will use the hardcoded path in the c code
# VERBOSE: actually show the commands used for compilation.
# WITH_NETWORK: enable networking
# DEDICATED: allows compilation on UNIX without SDL. Useful for dedicated servers
#
# Paths:
# INSTALL: If not set, the game uses the directory of the binary to
# store everything (lang, data, gm, save and openttd.cfg), this is the `old' behaviour.
# In this case, none of the following paths are used, you also should _not_
# use `make install', but copy the required stuff yourself (or just play out
# of you source directory, which should work fine).
# If you want to use `make install' to install the game globally, you should
# define it _before_ you build the game. If you only define INSTALL when you
# do `make install', the game won't be able to find it's files (so you should
# also define all the following paths before building).
#
# So, the following paths should be defined if INSTALL is defined.
# None of these paths have to end with /
# PREFIX:	Normally /usr/local
# BINARY_DIR:	The location of the binary, normally games. (Will be prefixed
#		with $PREFIX)
# DATA_DIR: 	The location of the data (lang, data and gm), normally
#		share/games/openttd. (Will be prefixed with $PREFIX)
# PERSONAL_DIR:	The directory where openttd.cfg and the save folder will be
#		stored. You cannot use ~ here, define USE_HOMEDIR for that.
# USE_HOMEDIR:	If this variable is set, PERSONAL_DIR will be prefixed with
#		~/ at runtime (the user's homedir)
# SECOND_DATA_PATH  Use this data dir if a file is not found in the data dir in the data path
# CUSTOM_LANG_PATH  If this is set, it will use the path given to search for lng files 
#		instead of the lang dir in the data path
#   NOTE: both SECOND_DATA_PATH and CUSTOM_LANG_PATH uses paths relative to where OTTD is opened
#
# DEST_DIR:	make install will use this directory instead of the filesystem
# 		root to install its files. This should normally not be used by
# 		ordinary users, currently it is only used for the debian
# 		packaging. This value should only be set when calling `make
# 		install' and is not saved in Makefile.config
#
# STATIC: link statically
# CYGWIN: build in Cygwin environment
# MINGW: build with MingW compiler, link with MingW libraries
#
# Experimental (does not work properly):
# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
