+"""Stuff to parse Sun and NeXT audio files.
+
+An audio file consists of a header followed by the data.  The structure
+of the header is as follows.
+
+        +---------------+
+        | magic word    |
+        +---------------+
+        | header size   |
+        +---------------+
+        | data size     |
+        +---------------+
+        | encoding      |
+        +---------------+
+        | sample rate   |
+        +---------------+
+        | # of channels |
+        +---------------+
+        | info          |
+        |               |
+        +---------------+
+
+The magic word consists of the 4 characters '.snd'.  Apart from the
+info field, all header fields are 4 bytes in size.  They are all
+32-bit unsigned integers encoded in big-endian byte order.
+
+The header size really gives the start of the data.
+The data size is the physical size of the data.  From the other
+parameters the number of frames can be calculated.
+The encoding gives the way in which audio samples are encoded.
+Possible values are listed below.
+The info field currently consists of an ASCII string giving a
+human-readable description of the audio file.  The info field is
+padded with NUL bytes to the header size.
+
+Usage.
+
+Reading audio files:
+        f = sunau.open(file, 'r')
+where file is either the name of a file or an open file pointer.
+The open file pointer must have methods read(), seek(), and close().
+When the setpos() and rewind() methods are not used, the seek()
+method is not  necessary.
+
+This returns an instance of a class with the following public methods:
+        getnchannels()  -- returns number of audio channels (1 for
+                           mono, 2 for stereo)
+        getsampwidth()  -- returns sample width in bytes
+        getframerate()  -- returns sampling frequency
+        getnframes()    -- returns number of audio frames
+        getcomptype()   -- returns compression type ('NONE' or 'ULAW')
+        getcompname()   -- returns human-readable version of
+                           compression type ('not compressed' matches 'NONE')
+        getparams()     -- returns a tuple consisting of all of the
+                           above in the above order
+        getmarkers()    -- returns None (for compatibility with the
+                           aifc module)
+        getmark(id)     -- raises an error since the mark does not
+                           exist (for compatibility with the aifc module)
+        readframes(n)   -- returns at most n frames of audio
+        rewind()        -- rewind to the beginning of the audio stream
+        setpos(pos)     -- seek to the specified position
+        tell()          -- return the current position
+        close()         -- close the instance (make it unusable)
+The position returned by tell() and the position given to setpos()
+are compatible and have nothing to do with the actual position in the
+file.
+The close() method is called automatically when the class instance
+is destroyed.
+
+Writing audio files:
+        f = sunau.open(file, 'w')
+where file is either the name of a file or an open file pointer.
+The open file pointer must have methods write(), tell(), seek(), and
+close().
+
+This returns an instance of a class with the following public methods:
+        setnchannels(n) -- set the number of channels
+        setsampwidth(n) -- set the sample width
+        setframerate(n) -- set the frame rate
+        setnframes(n)   -- set the number of frames
+        setcomptype(type, name)
+                        -- set the compression type and the
+                           human-readable compression type
+        setparams(tuple)-- set all parameters at once
+        tell()          -- return current position in output file
+        writeframesraw(data)
+                        -- write audio frames without pathing up the
+                           file header
+        writeframes(data)
+                        -- write audio frames and patch up the file header
+        close()         -- patch up the file header and close the
+                           output file
+You should set the parameters before the first writeframesraw or
+writeframes.  The total number of frames does not need to be set,
+but when it is set to the correct value, the header does not have to
+be patched up.
+It is best to first set all parameters, perhaps possibly the
+compression type, and then write audio frames using writeframesraw.
+When all frames have been written, either call writeframes('') or
+close() to patch up the sizes in the header.
+The close() method is called automatically when the class instance
+is destroyed.
