- * On systems capable of running the configure script, the configure process

-/* ================================================================ */
-
-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by curl/curl.h when an application is
- * being built using an already built libcurl library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the curlbuild.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * curl library user nor by the curl library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the libcurl development mailing list:
- * http://cool.haxx.se/mailman/listinfo/curl-library/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- *   "negative subscript or subscript is too large"
- *   "array must have at least one element"
- *   "-1 is an illegal array size"
- *   "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built libcurl library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.

-Game_Music_Emu 0.6.0 Design
---------------------------
-This might be slightly out-of-date at times, but will be a big help in
-understanding the library implementation.
-
-
-Architecture
------------
-The library is essentially a bunch of independent game music file
-emulators unified with a common interface.
-
-Gme_File and Music_Emu provide a common interface to the emulators. The
-virtual functions are protected rather than public to allow pre- and
-post-processing of arguments and data in one place. This allows the
-emulator classes to assume that everything is set up properly when
-starting a track and playing samples.
-
-All file input is done with the Data_Reader interface. Many derived
-classes are present, for the usual disk-based file and block of memory,
-to specialized adaptors for things like reading a subset of data or
-combining a block of memory with a Data_Reader to the remaining data.
-This makes the library much more flexible with regard to the source of
-game music file data. I still added a specialized load_mem() function to
-have the emulator keep a pointer to data already read in memory, for
-those formats whose files can be absolutely huge (GYM, some VGMs). This
-is important if for some reason the caller must load the data ahead of
-time, but doesn't want the emulator needlessly making a copy.
-
-Since silence checking and fading are relatively complex, they are kept
-separate from basic file loading and track information, which are
-handled in the base class Gme_File. My original intent was to use
-Gme_File as the common base class for full emulators and track
-information-only readers, but implementing the C interface was much
-simpler if both derived from Music_Emu. User C++ code can still benefit
-from static checking by using Gme_File where only track information will
-be accessed.
-
-Each emulator generally has three components: main emulator, CPU
-emulator, and sound chip emulator(s). Each component has minimal
-coupling, so use in a full emulator or stand alone is fairly easy. This
-modularity really helps reduce complexity. Blip_Buffer helps a lot with
-simplifying the APU interfaces and implementation.
-
-The "classic" emulators derive from Classic_Emu, which handles
-Blip_Buffer filling and multiple channels. It uses Multi_Buffer for
-output, allowing you to derive a custom buffer that could output each
-voice to a separate sound channel and do different processing on each.
-At some point I'm going to implement a better Effects_Buffer that allows
-individual control of every channel.
-
-In implementing the C interface, I wanted a way to specify an emulator
-type that didn't require linking in all the emulators. For each emulator
-type there is a global object with pointers to functions to create the
-emulator or a track information reader. The emulator type is thus a
-pointer to this, which conveniently allows for a NULL value. The user
-referencing this emulator type object is what ultimately links the
-emulator in (unless new Foo_Emu is used in C++, of course). This type
-also serves as a useful substitute for RTTI on older C++ compilers.
-
-Addendum: I have since added gme_type_list(), which causes all listed
-emulators to be linked in. To avoid this, I make the list itself
-editable in blargg_config.h. Having a built-in list allows
-gme_load_file() to take a path and give back an emulator with the file
-loaded, which is extremely useful for new users.
-
-
-Interface conventions
----------------------
-If a function retains a pointer to or replaces the value of an object
-passed, it takes a pointer so that it will be clear in the caller's
-source code that care is required.
-
-Multi-word names have an underscore '_' separator between individual
-words.
-
-Functions are named with lowercase words. Functions which perform an
-action with side-effects are named with a verb phrase (i.e. load, move,
-run). Functions which return the value of a piece of state are named
-using a noun phrase (i.e. loaded, moved, running).
-
-Classes are named with capitalized words. Only the first letter of an
-acronym is capitalized. Class names are nouns, sometimes suggestive of
-what they do (i.e. File_Scanner).
-
-Structure, enumeration, and typedefs to these and built-in types are
-named using lowercase words with a _t suffix.
-
-Macros are named with all-uppercase words.
-
-Internal names which can't be hidden due to technical reasons have an
-underscore '_' suffix.
-
-
-Managing Complexity
-------------------
-Complexity has been a factor in most library decisions. Many features
-have been passed by due to the complexity they would add. Once
-complexity goes past a certain level, it mentally grasping the library
-in its entirety, at which point more defects will occur and be hard to
-find.
-
-I chose 16-bit signed samples because it seems to be the most common
-format. Supporting multiple formats would add too much complexity to be
-worth it. Other formats can be obtained via conversion.
-
-I've kept interfaces fairly lean, leaving many possible features
-untapped but easy to add if necessary. For example the classic emulators
-could have volume and frequency equalization adjusted separately for
-each channel, since they each have an associated Blip_Synth.
-
-Source files of 400 lines or less seem to be the best size to limit
-complexity. In a few cases there is no reasonable way to split longer
-files, or there is benefit from having the source together in one file.
-
-
-Preventing Bugs
---------------
-I've done many things to reduce the opportunity for defects. A general
-principle is to write code so that defects will be as visible as
-possible. I've used several techniques to achieve this.
-
-I put assertions at key points where defects seem likely or where
-corruption due to a defect is likely to be visible. I've also put
-assertions where violations of the interface are likely. In emulators
-where I am unsure of exact hardware operation in a particular case, I
-output a debug-only message noting that this has occurred; many times I
-haven't implemented a hardware feature because nothing uses it. I've
-made code brittle where there is no clear reason flexibility; code
-written to handle every possibility sacrifices quality and reliability
-to handle vaguely defined situations.
-
-
-Flexibility through indirection
-------------------------------
-I've tried to allow the most flexibility of modules by using indirection
-to allow extension by the user. This keeps each module simpler and more
-focused on its unique task.
-
-The classic emulators use Multi_Buffer, which potentially allows a
-separate Blip_Buffer for each channel. This keeps emulators free of
-typical code to allow output in mono, stereo, panning, etc.
-
-All emulators use a reader object to access file data, allowing it to be
-stored in a regular file, compressed archive, memory, or generated
-on-the-fly. Again, the library can be kept free of the particulars of
-file access and changes required to support new formats.
-
-
-Emulators in general
--------------------
-When I wrote the first NES sound emulator, I stored most of the state in
-an emulator-specific format, with significant redundancy. In the
-register write function I decoded everything into named variables. I
-became tired of the verbosity and wanted to more closely model the
-hardware, so I moved to a style of storing the last written value to
-each register, along with as little other state as possible, mostly the
-internal hardware registers. While this involves slightly more
-recalculation, in most cases the emulation code is of comparable size.
-It also makes state save/restore (for use in a full emulator) much
-simpler. Finally, it makes debugging easier since the hardware registers
-used in emulation are obvious.
-
-
-CPU Cores
---------
-I've spent lots of time coming up with techniques to optimize the CPU
-cores. Some of the most important: execute multiple instructions during
-an emulation call, keep state in local variables to allow register
-assignment, optimize state representation for most common instructions,
-defer status flag calculation until actually needed, read program code
-directly without a call to the memory read function, always pre-fetch
-the operand byte before decoding instruction, and emulate instructions
-using common blocks of code.
-
-I've successfully used Nes_Cpu in a fairly complete NES emulator, and
-I'd like to make all the CPU emulators suitable for use in emulators. It
-seems a waste for them to be used only for the small amount of emulation
-necessary for game music files.
-
-I debugged the CPU cores by writing a test shell that ran them in
-parallel with other CPU cores and compared all memory accesses and
-processor states at each step. This provided good value at little cost.
-
-The CPU mapping page size is adjustable to allow the best tradeoff
-between memory/cache usage and handler granularity. The interface allows
-code to be somewhat independent of the page size.
-
-I optimize program memory accesses to direct reads rather than calls to
-the memory read function. My assumption is that it would be difficult to
-get useful code out of hardware I/O addresses, so no software will
-intentionally execute out of I/O space. Since the page size can be
-changed easily, most program memory mapping schemes can be accommodated.
-This greatly reduces memory access function calls.

-Overview
--------
-This library can open game music files, play tracks, and read game and
-track information tags. To play a game music file, do the following:
-
-* Open the file with gme_open_file()
-* Start a track with gme_start_track();
-* Generate samples as needed with gme_play()
-* Play samples through speaker using your operating system
-* Delete emulator when done with gme_delete()
-
-Your code must arrange for the generated samples to be played through
-the computer's speaker using whatever method your operating system
-requires.
-
-There are many additional features available; you can:
-
-* Determine of the type of a music file without opening it with
-gme_identify_*()
-* Load just the file's information tags with gme_info_only
-* Load from a block of memory rather than a file with gme_load_data()
-* Arrange for a fade-out at a particular time with gme_set_fade
-* Find when a track has ended with gme_track_ended()
-* Seek to a new time in the track with gme_seek()
-* Load an extended m3u playlist with gme_load_m3u()
-* Get a list of the voices (channels) and mute them individually with
-gme_voice_names() and gme_mute_voice()
-* Change the playback tempo without affecting pitch with gme_set_tempo()
-* Adjust treble/bass equalization with gme_set_equalizer()
-* Associate your own data with an emulator and later get it back with
-gme_set_user_data()
-* Register a function of yours to be called back when the emulator is
-deleted with gme_set_user_cleanup()
-
-Refer to gme.h for a comprehensive summary of features.
-
-
-Error handling
--------------
-Functions which can fail have a return type of gme_err_t, which is a
-pointer to an error string (const char*). If a function is successful it
-returns NULL. Errors that you can easily avoid are checked with debug
-assertions; gme_err_t return values are only used for genuine run-time
-errors that can't be easily predicted in advance (out of memory, I/O
-errors, incompatible file data). Your code should check all error
-values.
-
-When loading a music file in the wrong emulator or trying to load a
-non-music file, gme_wrong_file_type is returned. You can check for this
-error in C++ like this:
-
-	gme_err_t err = gme_open_file( path, &emu );
-	if ( err == gme_wrong_file_type )
-		...
-
-To check for minor problems, call gme_warning() to get a string
-describing the last warning. Your player should allow the user some way
-of knowing when this is the case, since these minor errors could affect
-playback. Without this information the user can't solve problems as
-well. When playing a track, gme_warning() returns minor playback-related
-problems (major playback problems end the track immediately and set the
-warning string).
-
-
-Emulator types
--------------
-The library includes several game music emulators that each support a
-different file type. Each is identified by a gme_type_t constant defined
-in gme.h, for example gme_nsf_emu is for the NSF emulator. If you use
-gme_open_file() or gme_open_data(), the library does the work of
-determining the file type and creating an appropriate emulator. If you
-want more control over this process, read on.
-
-There are two basic ways to identify a game music file's type: look at
-its file extension, or read the header data. The library includes
-functions to help with both methods. The first is preferable because it
-is fast and the most common way to identify files. Sometimes the
-extension is lost or wrong, so the header must be read.
-
-Use gme_identify_extension() to find the correct game music type based
-on a filename. To identify a file based on its extension and header
-contents, use gme_identify_file(). If you read the header data yourself,
-use gme_identify_header().
-
-If you want to remove support for some music types to reduce your
-executable size, edit GME_TYPE_LIST in blargg_config.h. For example, to
-support just NSF and GBS, use this:
-
-	#define GME_TYPE_LIST \
-		gme_nsf_type,\
-		gme_gbs_type
-
-
-M3U playlist support
--------------------
-The library supports playlists in an extended m3u format with
-gme_load_m3u() to give track names and times to multi-song formats: AY,
-GBS, HES, KSS, NSF, NSFE, and SAP. Some aspects of the file format
-itself is not well-defined so some m3u files won't work properly
-(particularly those provided with KSS files). Only m3u files referencing
-a single file are supported; your code must handle m3u files covering
-more than one game music file, though it can use the built-in m3u
-parsing provided by the library.
-
-
-Information fields
------------------
-Support is provided for the various text fields and length information
-in a file with gme_track_info(). If you just need track information for
-a file (for example, building a playlist), use gme_new_info() in place
-of gme_new_emu(), load the file normally, then you can access the track
-count and info, but nothing else.

-
-As listed above, the HES and KSS file formats don't include a track
-count, and tracks are often scattered over the 0-255 range, so an m3u
-playlist for these is a must.
-
-Unavailable text fields are set to an empty string and times to -1. Your
-code should be prepared for any combination of available and unavailable
-fields, as a particular music file might not use all of the supported
-fields listed above.
-
-Currently text fields are truncated to 255 characters. Obscure fields of
-some formats are not currently decoded; contact me if you want one
-added.
-
-
-Track length
------------
-The library leaves it up to you as to when to stop playing a track. You
-can ask for available length information and then tell the library what
-time it should start fading the track with gme_set_fade(). By default it
-also continually checks for 6 or more seconds of silence to mark the end
-of a track. Here is a reasonable algorithm you can use to decide how
-long to play a track:
-
-* If the track length is > 0, use it
-* If the loop length > 0, play for intro + loop * 2
-* Otherwise, default to 2.5 minutes (150000 msec)
-
-If you want to play a track longer than normal, be sure the loop length
-isn't zero. See Music_Player.cpp around line 145 for example code.
-
-By default, the library skips silence at the beginning of a track. It
-also continually checks for the end of a non-looping track by watching
-for 6 seconds of unbroken silence. When doing this is scans *ahead* by
-several seconds so it can report the end of the track after only one
-second of silence has actually played. This feature can be disabled with
-gme_ignore_silence().
-
-
-Loading file data
-----------------
-The library allows file data to be loaded in many different ways. All
-load functions return an error which you should check. The following
-examples assume these variables:
-
-	Music_Emu* emu;
-	gme_err_t error;
-
-If you're letting the library determine a file's type, you can use
-either gme_open_file() or gme_open_data():
-	
-	error = gme_open_file( pathname, &emu );
-	error = gme_open_data( pointer, size, &emu );
-
-If you're manually determining file type and using used gme_new_emu() to
-create an emulator, you can use the following methods of loading:
-
-* From a block of memory:
-
-	error = gme_load_data( emu, pointer, size );
-
-* Have library call your function to read data:
-
-	gme_err_t my_read( void* my_data, void* out, long count )
-	{
-		// code that reads 'count' bytes into 'out' buffer
-		// and return 0 if no error
-	}
-	
-	error = gme_load_custom( emu, my_read, file_size, my_data );
-
-
-Sound parameters
----------------
-All emulators support an arbitrary output sampling rate. A rate of 44100
-Hz should work well on most systems. Since band-limited synthesis is
-used, a sampling rate above 48000 Hz is not necessary and will actually
-reduce sound quality and performance.
-
-All emulators also support adjustable gain, mainly for the purpose of
-getting consistent volume between different music formats and avoiding
-excessive modulation. The gain can only be set *before* setting the
-emulator's sampling rate, so it's not useful as a general volume
-control. The default gains of emulators are set so that they give
-generally similar volumes, though some soundtracks are significantly
-louder or quieter than normal.
-
-Some emulators support adjustable treble and bass frequency equalization
-(AY, GBS, HES, KSS, NSF, NSFE, SAP, VGM) using set_equalizer().
-Parameters are specified using gme_equalizer_t eq = { treble_dB,
-bass_freq }. Treble_dB sets the treble level (in dB), where 0.0 dB gives
-normal treble; -200.0 dB is quite muffled, and 5.0 dB emphasizes treble
-for an extra crisp sound. Bass_freq sets the frequency where bass
-response starts to diminish; 15 Hz is normal, 0 Hz gives maximum bass,
-and 15000 Hz removes all bass. For example, the following makes the
-sound extra-crisp but lacking bass:
-
-	gme_equalizer_t eq = { 5.0, 1000 };
-	gme_set_equalizer( music_emu, &eq );
-
-Each emulator's equalization defaults to approximate the particular
-console's sound quality; this default can be determined by calling
-equalizer() just after creating the emulator. The Music_Emu::tv_eq
-profile gives sound as if coming from a TV speaker, and some emulators
-include other profiles for different versions of the system. For
-example, to use Famicom sound equalization with the NSF emulator, do the
-following:
-
-	music_emu->set_equalizer( Nsf_Emu::famicom_eq );
-
-
-VGM/GYM YM2413 & YM2612 FM sound
--------------------------------
-The library plays Sega Genesis/Mega Drive music using a YM2612 FM sound
-chip emulator based on the Gens project. Because this has some
-inaccuracies, other YM2612 emulators can be used in its place by
-re-implementing the interface in YM2612_Emu.h. Available on my website
-is a modified version of MAME's YM2612 emulator, which sounds better in
-some ways and whose author is still making improvements.
-
-VGM music files using the YM2413 FM sound chip are also supported, but a
-YM2413 emulator isn't included with the library due to technical
-reasons. I have put one of the available YM2413 emulators on my website
-that can be used directly.
-
-
-Modular construction
--------------------
-The library is made of many fairly independent modules. If you're using
-only one music file emulator, you can eliminate many of the library
-sources from your program. Refer to the files list in readme.txt to get
-a general idea of what can be removed, and be sure to edit GME_TYPE_LIST
-(see "Emulator types" above). Post to the forum if you'd like me to put
-together a smaller version for a particular use, as this only takes me a
-few minutes to do.
-
-If you want to use one of the individual sound chip emulators (or CPU
-cores) in your own console emulator, first check the libraries page on
-my website since I have released several of them as stand alone
-libraries with included documentation and examples on their use. If you
-don't find it as a standalone library, contact me and I'll consider
-separating it.
-
-The "classic" sound chips use my Blip_Buffer library, which greatly
-simplifies their implementation and efficiently handles band-limited
-synthesis. It is also available as a stand alone library with
-documentation and many examples.
-
-
-Obscure features
----------------
-The library's flexibility allows many possibilities. Contact me if you
-want help implementing ideas or removing limitations.
-
-* Uses no global/static variables, allowing multiple instances of any
-emulator. This is useful in a music player if you want to allow
-simultaneous recording or scanning of other tracks while one is already
-playing. This will also be useful if your platform disallows global
-data.
-
-* Emulators that support a custom sound buffer can have *every* voice
-routed to a different Blip_Buffer, allowing custom processing on each
-voice. For example you could record a Game Boy track as a 4-channel
-sound file.
-
-* Defining BLIP_BUFFER_FAST uses lower quality, less-multiply-intensive
-synthesis on "classic" emulators, which might help on some really old
-processors. This significantly lowers sound quality and prevents treble
-equalization. Try this if your platform's processor isn't fast enough
-for normal quality. Even on my ten-year-old 400 MHz Mac, this reduces
-processor usage at most by about 0.6% (from 4% to 3.4%), hardly worth
-the quality loss.
-
-
-Solving problems
----------------
-If you're having problems, try the following:
-
-* If you're getting garbled sound, try this simple siren generator in
-place of your call to play(). This will quickly tell whether the problem
-is in the library or in your code.
-
-	static void play_siren( long count, short* out )
-	{
-		static double a, a2;
-		while ( count-- )
-			*out++ = 0x2000 * sin( a += .1 + .05*sin( a2+=.00005 ) );
-	}
-
-* Enable debugging support in your environment. This enables assertions
-and other run-time checks.
-
-* Turn the compiler's optimizer is off. Sometimes an optimizer generates
-bad code.
-
-* If multiple threads are being used, ensure that only one at a time is
-accessing a given set of objects from the library. This library is not
-in general thread-safe, though independent objects can be used in
-separate threads.
-
-* If all else fails, see if the demos work.

+Overview
+--------
+This library can open game music files, play tracks, and read game and
+track information tags. To play a game music file, do the following:
+
+* Open the file with gme_open_file()
+* Start a track with gme_start_track();
+* Generate samples as needed with gme_play()
+* Play samples through speaker using your operating system
+* Delete emulator when done with gme_delete()
+
+Your code must arrange for the generated samples to be played through
+the computer's speaker using whatever method your operating system
+requires.
+
+There are many additional features available; you can:
+
+* Determine of the type of a music file without opening it with
+gme_identify_*()
+* Load just the file's information tags with gme_info_only
+* Load from a block of memory rather than a file with gme_load_data()
+* Arrange for a fade-out at a particular time with gme_set_fade
+* Find when a track has ended with gme_track_ended()
+* Seek to a new time in the track with gme_seek()
+* Load an extended m3u playlist with gme_load_m3u()
+* Get a list of the voices (channels) and mute them individually with
+gme_voice_names() and gme_mute_voice()
+* Change the playback tempo without affecting pitch with gme_set_tempo()
+* Adjust treble/bass equalization with gme_set_equalizer()
+* Associate your own data with an emulator and later get it back with
+gme_set_user_data()
+* Register a function of yours to be called back when the emulator is
+deleted with gme_set_user_cleanup()
+
+Refer to gme.h for a comprehensive summary of features.
+
+
+Error handling
+--------------
+Functions which can fail have a return type of gme_err_t, which is a
+pointer to an error string (const char*). If a function is successful it
+returns NULL. Errors that you can easily avoid are checked with debug
+assertions; gme_err_t return values are only used for genuine run-time
+errors that can't be easily predicted in advance (out of memory, I/O
+errors, incompatible file data). Your code should check all error
+values.
+
+When loading a music file in the wrong emulator or trying to load a
+non-music file, gme_wrong_file_type is returned. You can check for this
+error in C++ like this:
+
+	gme_err_t err = gme_open_file( path, &emu );
+	if ( err == gme_wrong_file_type )
+		...
+
+To check for minor problems, call gme_warning() to get a string
+describing the last warning. Your player should allow the user some way
+of knowing when this is the case, since these minor errors could affect
+playback. Without this information the user can't solve problems as
+well. When playing a track, gme_warning() returns minor playback-related
+problems (major playback problems end the track immediately and set the
+warning string).
+
+
+Emulator types
+--------------
+The library includes several game music emulators that each support a
+different file type. Each is identified by a gme_type_t constant defined
+in gme.h, for example gme_nsf_emu is for the NSF emulator. If you use
+gme_open_file() or gme_open_data(), the library does the work of
+determining the file type and creating an appropriate emulator. If you
+want more control over this process, read on.
+
+There are two basic ways to identify a game music file's type: look at
+its file extension, or read the header data. The library includes
+functions to help with both methods. The first is preferable because it
+is fast and the most common way to identify files. Sometimes the
+extension is lost or wrong, so the header must be read.
+
+Use gme_identify_extension() to find the correct game music type based
+on a filename. To identify a file based on its extension and header
+contents, use gme_identify_file(). If you read the header data yourself,
+use gme_identify_header().
+
+If you want to remove support for some music types to reduce your
+executable size, edit GME_TYPE_LIST in blargg_config.h. For example, to
+support just NSF and GBS, use this:
+
+	#define GME_TYPE_LIST \
+		gme_nsf_type,\
+		gme_gbs_type
+
+
+M3U playlist support
+--------------------
+The library supports playlists in an extended m3u format with
+gme_load_m3u() to give track names and times to multi-song formats: AY,
+GBS, HES, KSS, NSF, NSFE, and SAP. Some aspects of the file format
+itself is not well-defined so some m3u files won't work properly
+(particularly those provided with KSS files). Only m3u files referencing
+a single file are supported; your code must handle m3u files covering
+more than one game music file, though it can use the built-in m3u
+parsing provided by the library.
+
+
+Information fields
+------------------
+Support is provided for the various text fields and length information
+in a file with gme_track_info(). If you just need track information for
+a file (for example, building a playlist), use gme_new_info() in place
+of gme_new_emu(), load the file normally, then you can access the track
+count and info, but nothing else.

+
+As listed above, the HES and KSS file formats don't include a track
+count, and tracks are often scattered over the 0-255 range, so an m3u
+playlist for these is a must.
+
+Unavailable text fields are set to an empty string and times to -1. Your
+code should be prepared for any combination of available and unavailable
+fields, as a particular music file might not use all of the supported
+fields listed above.
+
+Currently text fields are truncated to 255 characters. Obscure fields of
+some formats are not currently decoded; contact me if you want one
+added.
+
+
+Track length
+------------
+The library leaves it up to you as to when to stop playing a track. You
+can ask for available length information and then tell the library what
+time it should start fading the track with gme_set_fade(). By default it
+also continually checks for 6 or more seconds of silence to mark the end
+of a track. Here is a reasonable algorithm you can use to decide how
+long to play a track:
+
+* If the track length is > 0, use it
+* If the loop length > 0, play for intro + loop * 2
+* Otherwise, default to 2.5 minutes (150000 msec)
+
+If you want to play a track longer than normal, be sure the loop length
+isn't zero. See Music_Player.cpp around line 145 for example code.
+
+By default, the library skips silence at the beginning of a track. It
+also continually checks for the end of a non-looping track by watching
+for 6 seconds of unbroken silence. When doing this is scans *ahead* by
+several seconds so it can report the end of the track after only one
+second of silence has actually played. This feature can be disabled with
+gme_ignore_silence().
+
+
+Loading file data
+-----------------
+The library allows file data to be loaded in many different ways. All
+load functions return an error which you should check. The following
+examples assume these variables:
+
+	Music_Emu* emu;
+	gme_err_t error;
+
+If you're letting the library determine a file's type, you can use
+either gme_open_file() or gme_open_data():
+	
+	error = gme_open_file( pathname, &emu );
+	error = gme_open_data( pointer, size, &emu );
+
+If you're manually determining file type and using used gme_new_emu() to
+create an emulator, you can use the following methods of loading:
+
+* From a block of memory:
+
+	error = gme_load_data( emu, pointer, size );
+
+* Have library call your function to read data:
+
+	gme_err_t my_read( void* my_data, void* out, long count )
+	{
+		// code that reads 'count' bytes into 'out' buffer
+		// and return 0 if no error
+	}
+	
+	error = gme_load_custom( emu, my_read, file_size, my_data );
+
+
+Sound parameters
+----------------
+All emulators support an arbitrary output sampling rate. A rate of 44100
+Hz should work well on most systems. Since band-limited synthesis is
+used, a sampling rate above 48000 Hz is not necessary and will actually
+reduce sound quality and performance.
+
+All emulators also support adjustable gain, mainly for the purpose of
+getting consistent volume between different music formats and avoiding
+excessive modulation. The gain can only be set *before* setting the
+emulator's sampling rate, so it's not useful as a general volume
+control. The default gains of emulators are set so that they give
+generally similar volumes, though some soundtracks are significantly
+louder or quieter than normal.
+
+Some emulators support adjustable treble and bass frequency equalization
+(AY, GBS, HES, KSS, NSF, NSFE, SAP, VGM) using set_equalizer().
+Parameters are specified using gme_equalizer_t eq = { treble_dB,
+bass_freq }. Treble_dB sets the treble level (in dB), where 0.0 dB gives
+normal treble; -200.0 dB is quite muffled, and 5.0 dB emphasizes treble
+for an extra crisp sound. Bass_freq sets the frequency where bass
+response starts to diminish; 15 Hz is normal, 0 Hz gives maximum bass,
+and 15000 Hz removes all bass. For example, the following makes the
+sound extra-crisp but lacking bass:
+
+	gme_equalizer_t eq = { 5.0, 1000 };
+	gme_set_equalizer( music_emu, &eq );
+
+Each emulator's equalization defaults to approximate the particular
+console's sound quality; this default can be determined by calling
+equalizer() just after creating the emulator. The Music_Emu::tv_eq
+profile gives sound as if coming from a TV speaker, and some emulators
+include other profiles for different versions of the system. For
+example, to use Famicom sound equalization with the NSF emulator, do the
+following:
+
+	music_emu->set_equalizer( Nsf_Emu::famicom_eq );
+
+
+VGM/GYM YM2413 & YM2612 FM sound
+--------------------------------
+The library plays Sega Genesis/Mega Drive music using a YM2612 FM sound
+chip emulator based on the Gens project. Because this has some
+inaccuracies, other YM2612 emulators can be used in its place by
+re-implementing the interface in YM2612_Emu.h. Available on my website
+is a modified version of MAME's YM2612 emulator, which sounds better in
+some ways and whose author is still making improvements.
+
+VGM music files using the YM2413 FM sound chip are also supported, but a
+YM2413 emulator isn't included with the library due to technical
+reasons. I have put one of the available YM2413 emulators on my website
+that can be used directly.
+
+
+Modular construction
+--------------------
+The library is made of many fairly independent modules. If you're using
+only one music file emulator, you can eliminate many of the library
+sources from your program. Refer to the files list in readme.txt to get
+a general idea of what can be removed, and be sure to edit GME_TYPE_LIST
+(see "Emulator types" above). Post to the forum if you'd like me to put
+together a smaller version for a particular use, as this only takes me a
+few minutes to do.
+
+If you want to use one of the individual sound chip emulators (or CPU
+cores) in your own console emulator, first check the libraries page on
+my website since I have released several of them as stand alone
+libraries with included documentation and examples on their use. If you
+don't find it as a standalone library, contact me and I'll consider
+separating it.
+
+The "classic" sound chips use my Blip_Buffer library, which greatly
+simplifies their implementation and efficiently handles band-limited
+synthesis. It is also available as a stand alone library with
+documentation and many examples.
+
+
+Obscure features
+----------------
+The library's flexibility allows many possibilities. Contact me if you
+want help implementing ideas or removing limitations.
+
+* Uses no global/static variables, allowing multiple instances of any
+emulator. This is useful in a music player if you want to allow
+simultaneous recording or scanning of other tracks while one is already
+playing. This will also be useful if your platform disallows global
+data.
+
+* Emulators that support a custom sound buffer can have *every* voice
+routed to a different Blip_Buffer, allowing custom processing on each
+voice. For example you could record a Game Boy track as a 4-channel
+sound file.
+
+* Defining BLIP_BUFFER_FAST uses lower quality, less-multiply-intensive
+synthesis on "classic" emulators, which might help on some really old
+processors. This significantly lowers sound quality and prevents treble
+equalization. Try this if your platform's processor isn't fast enough
+for normal quality. Even on my ten-year-old 400 MHz Mac, this reduces
+processor usage at most by about 0.6% (from 4% to 3.4%), hardly worth
+the quality loss.
+
+
+Solving problems
+----------------
+If you're having problems, try the following:
+
+* If you're getting garbled sound, try this simple siren generator in
+place of your call to play(). This will quickly tell whether the problem
+is in the library or in your code.
+
+	static void play_siren( long count, short* out )
+	{
+		static double a, a2;
+		while ( count-- )
+			*out++ = 0x2000 * sin( a += .1 + .05*sin( a2+=.00005 ) );
+	}
+
+* Enable debugging support in your environment. This enables assertions
+and other run-time checks.
+
+* Turn the compiler's optimizer is off. Sometimes an optimizer generates
+bad code.
+
+* If multiple threads are being used, ensure that only one at a time is
+accessing a given set of objects from the library. This library is not
+in general thread-safe, though independent objects can be used in
+separate threads.
+
+* If all else fails, see if the demos work.
+

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-
-Getting Started
---------------
-Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
-all source files in gme/.
-
-Or, if you have CMake 2.6 or later, execute at a command prompt (from the
-extracted source directory):
-
-    mkdir build
-    cd build
-    cmake ../         # <-- Pass any needed CMake flags here
-    make              # To build the library
-    cd demo
-    make              # To build the demo itself
-
-Be sure "test.nsf" is in the same directory as the demo program. Running it
-should generate the recording "out.wav".
-
-You can use "make install" to install the library. To choose where to install
-the library to, use the CMake argument "-DCMAKE_INSTALL_PREFIX=/usr/local"
-(and replace /usr/local with the base path you wish to use). Alternately, you
-can specify the base path to install to when you run "make install" by passing
-'DESTDIR=/usr/local' on the make install command line (again, replace
-/usr/local as appropriate).
-
-To build a static library instead of shared (the default), pass
-DBUILD_SHARED_LIBS=OFF to the cmake command when running cmake.
-
-A slightly more extensive demo application is available in the player/
-directory.  It requires SDL to build.
-
-Read gme.txt for more information. Post to the discussion forum for
-assistance.

+Game_Music_Emu 0.6.2: Game Music Emulators
+------------------------------------------
+Game_Music_Emu is a collection of video game music file emulators that
+support the following formats and systems:
+
+AY        ZX Spectrum/Amstrad CPC
+GBS       Nintendo Game Boy
+GYM       Sega Genesis/Mega Drive
+HES       NEC TurboGrafx-16/PC Engine
+KSS       MSX Home Computer/other Z80 systems (doesn't support FM sound)
+NSF/NSFE  Nintendo NES/Famicom (with VRC 6, Namco 106, and FME-7 sound)
+SAP       Atari systems using POKEY sound chip
+SPC       Super Nintendo/Super Famicom
+VGM/VGZ   Sega Master System/Mark III, Sega Genesis/Mega Drive,BBC Micro
+
+Features:
+* C interface for use in C, C++, and other compatible languages
+* High emphasis has been placed on making the library very easy to use
+* One set of common functions work with all emulators the same way
+* Several code examples, including music player using SDL
+* Portable code for use on any system with modern or older C++ compilers
+* Adjustable output sample rate using quality band-limited resampling
+* Uniform access to text information fields and track timing information
+* End-of-track fading and automatic look ahead silence detection
+* Treble/bass and stereo echo for AY/GBS/HES/KSS/NSF/NSFE/SAP/VGM
+* Tempo can be adjusted and individual voices can be muted while playing
+* Can read music data from file, memory, or custom reader function/class
+* Can access track information without having to load into full emulator
+* M3U track listing support for multi-track formats
+* Modular design allows elimination of unneeded emulators/features
+
+This library has been used in game music players for Windows, Linux on
+several architectures, Mac OS, MorphOS, Xbox, PlayStation Portable,
+GP2X, and Nintendo DS.

+
+Getting Started
+---------------
+Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
+all source files in gme/.
+
+Or, if you have CMake 2.6 or later, execute at a command prompt (from the
+extracted source directory):
+
+    mkdir build
+    cd build
+    cmake ../         # <-- Pass any needed CMake flags here
+    make              # To build the library
+    cd demo
+    make              # To build the demo itself
+
+Be sure "test.nsf" is in the same directory as the demo program. Running it
+should generate the recording "out.wav".
+
+You can use "make install" to install the library. To choose where to install
+the library to, use the CMake argument "-DCMAKE_INSTALL_PREFIX=/usr/local"
+(and replace /usr/local with the base path you wish to use). Alternately, you
+can specify the base path to install to when you run "make install" by passing
+'DESTDIR=/usr/local' on the make install command line (again, replace
+/usr/local as appropriate).
+
+To build a static library instead of shared (the default), pass
+-DBUILD_SHARED_LIBS=OFF to the cmake command when running cmake.
+
+A slightly more extensive demo application is available in the player/
+directory.  It requires SDL to build.
+
+Read gme.txt for more information. Post to the discussion forum for
+assistance.
