-     The 'zlib' compression library provides in-memory compression and

-  decompression functions, including integrity checks of the uncompressed

-  data.  This version of the library supports only one compression method

-  (deflation) but other algorithms will be added later and will have the same

-  stream interface.

-

-     Compression can be done in a single step if the buffers are large

-  enough (for example if an input file is mmap'ed), or can be done by

-  repeated calls of the compression function.  In the latter case, the

-  application must provide more input and/or consume the output

-  (providing more output space) before each call.

-

-     The library also supports reading and writing files in gzip (.gz) format

-  with an interface similar to that of stdio.

-

-     The library does not install any signal handler. The decoder checks

-  the consistency of the compressed data, so the library should never

-  crash even in case of corrupted input.

-    deflate compresses as much data as possible, and stops when the input

-  buffer becomes empty or the output buffer becomes full. It may introduce some

-  output latency (reading input without producing any output) except when

-  forced to flush.

-

-    The detailed semantics are as follows. deflate performs one or both of the

-  following actions:

-

-  - Compress more input starting at next_in and update next_in and avail_in

-    accordingly. If not all input can be processed (because there is not

-    enough room in the output buffer), next_in and avail_in are updated and

-    processing will resume at this point for the next call of deflate().

-

-  - Provide more output starting at next_out and update next_out and avail_out

-    accordingly. This action is forced if the parameter flush is non zero.

-    Forcing flush frequently degrades the compression ratio, so this parameter

-    should be set only when necessary (in interactive applications).

-    Some output may be provided even if flush is not set.

-

-  Before the call of deflate(), the application should ensure that at least

-  one of the actions is possible, by providing more input and/or consuming

-  more output, and updating avail_in or avail_out accordingly; avail_out

-  should never be zero before the call. The application can consume the

-  compressed output when it wants, for example when the output buffer is full

-  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK

-  and with zero avail_out, it must be called again after making room in the

-  output buffer because there might be more output pending.

-

-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is

-  flushed to the output buffer and the output is aligned on a byte boundary, so

-  that the decompressor can get all input data available so far. (In particular

-  avail_in is zero after the call if enough output space has been provided

-  before the call.)  Flushing may degrade compression for some compression

-  algorithms and so it should be used only when necessary.

-

-    If flush is set to Z_FULL_FLUSH, all output is flushed as with

-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can

-  restart from this point if previous compressed data has been damaged or if

-  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade

-  the compression.

-

-    If deflate returns with avail_out == 0, this function must be called again

-  with the same value of the flush parameter and more output space (updated

-  avail_out), until the flush is complete (deflate returns with non-zero

-  avail_out).

-

-    If the parameter flush is set to Z_FINISH, pending input is processed,

-  pending output is flushed and deflate returns with Z_STREAM_END if there

-  was enough output space; if deflate returns with Z_OK, this function must be

-  called again with Z_FINISH and more output space (updated avail_out) but no

-  more input data, until it returns with Z_STREAM_END or an error. After

-  deflate has returned Z_STREAM_END, the only possible operations on the

-  stream are deflateReset or deflateEnd.

-  

-    Z_FINISH can be used immediately after deflateInit if all the compression

-  is to be done in a single step. In this case, avail_out must be at least

-  0.1% larger than avail_in plus 12 bytes.  If deflate does not return

-  Z_STREAM_END, then it must be called again as described above.

-

-    deflate() sets strm->adler to the adler32 checksum of all input read

-  so far (that is, total_in bytes).

-

-    deflate() may update data_type if it can make a good guess about

-  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered

-  binary. This field is only for information purposes and does not affect

-  the compression algorithm in any manner.

-

-    deflate() returns Z_OK if some progress has been made (more input

-  processed or more output produced), Z_STREAM_END if all input has been

-  consumed and all output has been produced (only when flush is set to

-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

-

-     The method parameter is the compression method. It must be Z_DEFLATED in

-   this version of the library.

-

-     The windowBits parameter is the base two logarithm of the window size

-   (the size of the history buffer).  It should be in the range 8..15 for this

-   version of the library. Larger values of this parameter result in better

-   compression at the expense of memory usage. The default value is 15 if

-   deflateInit is used instead.

-

-     The memLevel parameter specifies how much memory should be allocated

-   for the internal compression state. memLevel=1 uses minimum memory but

-   is slow and reduces compression ratio; memLevel=9 uses maximum memory

-   for optimal speed. The default value is 8. See zconf.h for total memory

-   usage as a function of windowBits and memLevel.

-

-     The strategy parameter is used to tune the compression algorithm. Use the

-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a

-   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no

-   string match).  Filtered data consists mostly of small values with a

-   somewhat random distribution. In this case, the compression algorithm is

-   tuned to compress them better. The effect of Z_FILTERED is to force more

-   Huffman coding and less string matching; it is somewhat intermediate

-   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects

-   the compression ratio but not the correctness of the compressed output even

-   if it is not set appropriately.

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may introduce some
+  output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows. deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far. (In particular
+  avail_in is zero after the call if enough output space has been provided
+  before the call.)  Flushing may degrade compression for some compression
+  algorithms and so it should be used only when necessary.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+  the compression.
+
+    If deflate returns with avail_out == 0, this function must be called again

+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,

+  was enough output space; if deflate returns with Z_OK, this function must be

+  more input data, until it returns with Z_STREAM_END or an error. After
+  deflate has returned Z_STREAM_END, the only possible operations on the
+  stream are deflateReset or deflateEnd.
+  
+    Z_FINISH can be used immediately after deflateInit if all the compression
+  is to be done in a single step. In this case, avail_out must be at least

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full. It may some
+  introduce some output latency (reading input without producing any output)
+  except when forced to flush.
+
+  The detailed semantics are as follows. inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly. If not all input can be processed (because there is not
+    enough room in the output buffer), next_in is updated and processing
+    will resume at this point for the next call of inflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there
+    is no more input data or no more space in the output buffer (see below
+    about the flush parameter).
+
+  Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating the next_* and avail_* values accordingly.
+  The application can consume the uncompressed output when it wants, for
+  example when the output buffer is full (avail_out == 0), or after each
+  call of inflate(). If inflate returns Z_OK and with zero avail_out, it
+  must be called again after making room in the output buffer because there
+  might be more output pending.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
+  output as possible to the output buffer. The flushing behavior of inflate is
+  not specified for values of the flush parameter other than Z_SYNC_FLUSH
+  and Z_FINISH, but the current implementation actually flushes as much output
+  as possible anyway.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error. However if all decompression is to be performed in a single step
+  (a single call of inflate), the parameter flush should be set to
+  Z_FINISH. In this case all pending input is processed and all pending
+  output is flushed; avail_out must be large enough to hold all the
+  uncompressed data. (The size of the uncompressed data may have been saved
+  by the compressor for this purpose.) The next operation on this stream must
+  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
+  is never required, but can be used to inform inflate that a faster routine
+  may be used for the single inflate() call.
+
+     If a preset dictionary is needed at this point (see inflateSetDictionary
+  below), inflate sets strm-adler to the adler32 checksum of the
+  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise 
+  it sets strm->adler to the adler32 checksum of all output produced
+  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
+  an error code as described below. At the end of the stream, inflate()
+  checks that its computed adler32 checksum is equal to that saved by the
+  compressor and returns Z_STREAM_END only if the checksum is correct.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect
+  adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
+  (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
+  enough memory, Z_BUF_ERROR if no progress is possible or if there was not
+  enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR

+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library. Larger values of this parameter result in better
+   compression at the expense of memory usage. The default value is 15 if
+   deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.
