+Version 0.1, 2.4.1997:
+
+ - the first released version
+
+5.4.1997:
+
+ - audio sync added before changing parameters
+
+Version 0.2, 9.4.1997:
+
+ - it was useless to start producer as a thread;
+ it was made that way just for historical reasons.
+ only consumer is threaded now. this may result
+ as more robust behaviour.
+
+ - there are min and max sizes for block now. i'm
+ not sure yet what size for a block and the audio
+ buffer would be good. needs more research.
+
+ - fill_buffer function. fills the audio buffer
+ before use.
+
+Version 0.2.1, 15.4.1997:
+
+ - signal() seems to be a bad idea in a threaded
+ application like this. causes kernel oops in
+ the sound driver function audio_write (sometimes).
+ let's have faith on the kernel and remove it.
+
+Version 0.2.2, 17.4.1997 morning:
+
+ - the last block was written from very wrong point.
+
+ - block counting added. this makes stream ending
+ simpler and (hopefully) more robust.
+
+ - first lines for handling underflow (buffer empty)
+ situation.
+
+Version 0.3, 17.4.1997 afternoon:
+
+ - underflow handling should work now.
+
+ - function buffer_usage added. returns buffer usage
+ in percents. nowhere used yet.
+
+ - minimum block size increased to 16k.
+
+Version 0.3.1, 19.4.1997:
+
+ - GNU style options.
+
+ - option -v (or --version) added.
+
+ - buffer usage option -u (or --usage) added.
+
+Version 0.4, 2.5.1997:
+
+ - support for RIFF/WAVE (WAV) and Sun audio
+ (AU) files.
+
+ - swap endianness flag -x (or --swap) added.
+
+ - verbose mode flag -V (or --verbose) added.
+
+ - force raw flag -r (or --raw) added. WAV- or
+ AU-file headers are ignored if this flag is set.
+
+Version 0.4.1, 3.5.1997:
+
+ - sun header gives odd aligned starting point
+ for sample. temporary fix.
+
+ - read_big_endian_long returned wrong value if
+ sampling rate was 44100. this caused tplay
+ not to work with that speed when playing sun
+ audio or wav file. fixed now.
+
+Version 0.4.2, 7.5.1997:
+
+ - read_big_endian_long and similar functions:
+ parameter's type was char* and that was a bug.
+ changed to byte* (unsigned char *). conversion
+ should also be saner now.
+
+ - force playing -f (or --force) flag added. this
+ makes tplay to ignore sound driver's results
+ when changing parameters.
+
+Version 0.4.3, 12.5.1997:
+
+ - binary is statically linked to LinuxThreads
+ version 0.6 now.
+
+ - print sun header comment if verbose is requested.
+
+ - sun audio file's data stream starting pointer
+ is read and set from the header.
+
+ - to avoid rounding errors when playing 16bit
+ and/or stereo (au or wav) sample, data section
+ is moved now to the beginning of buffer before
+ playing.
+
+Version 0.5, 23.10.1997:
+
+ - set_audio_parameters() partly rewritten and
+ changes to open_audio().
+
+ - in some WAV-files, data-portion is not started
+ with 'data'-magic but 'INFO' instead. some
+ players don't even check that so tplay prints
+ just a warning message now if neither of these
+ magics exists.
+
+Version 0.5.1, 25.10.1997:
+
+ - printing of buffer usage changed from producer
+ to consumer. this makes this silly feature a bit
+ more informative as it is still active after the
+ producer has stopped. underflow situation (when
+ the big buffer needs to be refilled) is also
+ possible to show now.
+
+Version 0.5.2, 9.5.1998:
+
+ - Jerko Golubovic <jerko.golubovic@public.srce.hr>
+ kindly modified the code to support those soundcards
+ that may result slightly different sampling rate
+ than requested. he also provided RPM of tplay.
+
+ - added -D (or --device=DEVICE) flag for setting
+ audio device to be used.
+
+ - added feature to -B (or --buffer-size=SIZE) flag.
+ buffer size can be given in seconds now, too.
+
+Version 0.5.3, 11.5.1998:
+
+ - rewrite of playing routine to support multiple
+ sound samples from command line.
+
+Version 0.5.4, 19.5.1998:
+
+ - added -l (or --loop) flag to support looping sound
+ samples.
+
+ - sun port.
+
+Version 0.5.5, 24.5.1998:
+
+ - added environment variable TPLAYDEV, which sets the
+ audio device to be used. decoding of command line
+ options is moved from main() to another function.
