-
-// This file contains:
-//
-//  - two stream buffer classes (ZlibCompressorIStreambuf and
-//    ZlibDecompressorIStreambuf), both based on the same abstract class:
-//    ZlibAbstractIStreambuf;
-//
-//  - two std::istream subclasses (ZlibCompressorIStream and
-//    ZlibDecompressorIStream), each creating and using the corresponding
-//    stream buffer class from the previous item.
-//
-// All these allow one to work with RFC 1950 and RFC 1952 compression
-// formats, respectively known as the zlib and gzip formats.
-//
-// These classes are *input* streaming classes, which means they can
-// efficiently handle arbitrary amounts of data without using any disk
-// space nor increasing amounts of memory, and allow “client code” to pull
-// exactly as much data as it wants at any given time, resuming later
-// when it is ready to handle the next chunk.
-//
-// So, for example, assuming you've created an instance of
-// ZlibCompressorIStream (bound to some input stream of your choice, let's
-// call it iStream), you could read 512 bytes of data from it, and you
-// would get the first 512 bytes of *compressed* data corresponding to what
-// iStream provided. Then you could resume at any time and ask for the next
-// 512 bytes of compressed data (or any other amount), etc.
-//
-// Therefore, these classes are well suited, among others, to compress or
-// decompress data streams while at the same time packing the result into
-// discrete chunks or packets with size constraints (you can think of the
-// process as making sausages :).
-//
-// The input being in each case an std::istream (for compressing as well as
-// for decompressing), it can be tied to an arbitrary source: a file with
-// sg_ifstream or std::ifstream, a memory buffer with std::istringstream or
-// std::stringstream, a TCP socket with a custom std::streambuf subclass[1]
-// to interface with the sockets API, etc.
-//
-//   [1] Possibly wrapped in an std::istream.
-//
-// The stream buffer classes upon which ZlibCompressorIStream and
-// ZlibDecompressorIStream are built have an xsgetn() implementation that
-// avoids useless copies of data by asking zlib to write directly to the
-// destination buffer. This xsgetn() method is used when calling read() on
-// the std::istream subclasses, or sgetn() if you are using the stream
-// buffer classes directly (i.e., ZlibCompressorIStreambuf and
-// ZlibDecompressorIStreambuf). Other std::istream methods may instead rely
-// only on the internal buffer and the underflow() method, and therefore be
-// less efficient for large amounts of data. You may want to take a look at
-// zlibstream_test.cxx to see various ways of using these classes.
-//
-// In case you use std::istream& operator>>(std::istream&, std::string&) or
-// its overload friends, beware that it splits fields at spaces, and by
-// default ignores spaces at the beginning of a field (cf. std::skipws,
-// std::noskipws and friends). As far as I understand it, most of these
-// operators are mainly intended in the IOStreams library to be used to
-// read an int here, a double there, a space-delimited string afterwards,
-// etc. (the exception could be the overload writing to a stream buffer,
-// however it doesn't seem to be very efficient on my system with GNU
-// libstdc++ [it is not using xsgetn()], so beware also of this one if you
-// are handling large amounts of data). For moderately complex or large
-// input handling, I'd suggest to use std::istream methods such as read(),
-// gcount() and getline() (std::getline() can be useful too). Or directly
-// use the stream buffer classes, in particular with sgetn().

-   *  @param iStream     Input stream to read from.
-   *  @param path        Optional path to the file corresponding to iStream,
-   *                     if any. Only used for error messages.
-   *  @param inBuf       Pointer to the input buffer (data read from iStream is
-   *                     written there before being compressed or decompressed).
-   *                     If nullptr, the buffer is allocated on the heap in the
-   *                     constructor and deallocated in the destructor.
-   *  @param inBufSize   Size of the input buffer, in chars.
-   *  @param outBuf      Pointer to the output buffer. Data is read by zlib
-   *                     from the input buffer, compressed or decompressed, and
-   *                     the result is directly written to the output buffer.
-   *                     If nullptr, the buffer is allocated on the heap in the
-   *                     constructor and deallocated in the destructor.
-   *  @param outBufSize  Size of the output buffer, in chars.
-   *  @param putbackSize Size of the putback area inside the output buffer, in
-   *                     chars.
-   *
-   *  It is required that putbackSize < outBufSize. It is guaranteed that,
-   *  if at least putbackSize chars have been read without any putback (or
-   *  unget) operation intermixed, then at least putbackSize chars can be
-   *  put back in sequence. If you don't need this feature, use zero for the
-   *  putbackSize value (the default) for best performance.
