+/// ZIP archive.
+/** \class QuaZip quazip.h <quazip/quazip.h>
+ * This class implements basic interface to the ZIP archive. It can be
+ * used to read table contents of the ZIP archive and retreiving
+ * information about the files inside it.
+ *
+ * You can also use this class to open files inside archive by passing
+ * pointer to the instance of this class to the constructor of the
+ * QuaZipFile class. But see QuaZipFile::QuaZipFile(QuaZip*, QObject*)
+ * for the possible pitfalls.
+ *
+ * This class is indended to provide interface to the ZIP subpackage of
+ * the ZIP/UNZIP package as well as to the UNZIP subpackage. But
+ * currently it supports only UNZIP.
+ *
+ * The use of this class is simple - just create instance using
+ * constructor, then set ZIP archive file name using setFile() function
+ * (if you did not passed the name to the constructor), then open() and
+ * then use different functions to work with it! Well, if you are
+ * paranoid, you may also wish to call close before destructing the
+ * instance, to check for errors on close.
+ *
+ * You may also use getUnzFile() and getZipFile() functions to get the
+ * ZIP archive handle and use it with ZIP/UNZIP package API directly.
+ *
+ * This class supports localized file names inside ZIP archive, but you
+ * have to set up proper codec with setCodec() function. By default,
+ * locale codec will be used, which is probably ok for UNIX systems, but
+ * will almost certainly fail with ZIP archives created in Windows. This
+ * is because Windows ZIP programs have strange habit of using DOS
+ * encoding for file names in ZIP archives. For example, ZIP archive
+ * with cyrillic names created in Windows will have file names in \c
+ * IBM866 encoding instead of \c WINDOWS-1251. I think that calling one
+ * function is not much trouble, but for true platform independency it
+ * would be nice to have some mechanism for file name encoding auto
+ * detection using locale information. Does anyone know a good way to do
+ * it?

+ * set explicitly via setIoDevice() or the QuaZip(QIODevice*)
+ * constructor, or it is created internally when opening the archive
+ * by its file name. The default API (qioapi.cpp) just delegates
+ * everything to the QIODevice API. Not only this allows to use a
+ * QIODevice instead of file name, but also has a nice side effect
+ * of raising the file size limit from 2G to 4G.

+/// A file inside ZIP archive.
+/** \class QuaZipFile quazipfile.h <quazip/quazipfile.h>
+ * This is the most interesting class. Not only it provides C++
+ * interface to the ZIP/UNZIP package, but also integrates it with Qt by
+ * subclassing QIODevice. This makes possible to access files inside ZIP
+ * archive using QTextStream or QDataStream, for example. Actually, this
+ * is the main purpose of the whole QuaZIP library.
+ *
+ * You can either use existing QuaZip instance to create instance of
+ * this class or pass ZIP archive file name to this class, in which case
+ * it will create internal QuaZip object. See constructors' descriptions
+ * for details. Writing is only possible with the existing instance.
+ *
+ * Note that due to the underlying library's limitation it is not
+ * possible to use multiple QuaZipFile instances to open several files
+ * in the same archive at the same time. If you need to write to
+ * multiple files in parallel, then you should write to temporary files
+ * first, then pack them all at once when you have finished writing. If
+ * you need to read multiple files inside the same archive in parallel,
+ * you should extract them all into a temporary directory first.
+ *
+ * \section quazipfile-sequential Sequential or random-access?
+ *
+ * At the first thought, QuaZipFile has fixed size, the start and the
+ * end and should be therefore considered random-access device. But
+ * there is one major obstacle to making it random-access: ZIP/UNZIP API
+ * does not support seek() operation and the only way to implement it is
+ * through reopening the file and re-reading to the required position,
+ * but this is prohibitively slow.
+ *
+ * Therefore, QuaZipFile is considered to be a sequential device. This
+ * has advantage of availability of the ungetChar() operation (QIODevice
+ * does not implement it properly for non-sequential devices unless they
+ * support seek()). Disadvantage is a somewhat strange behaviour of the
+ * size() and pos() functions. This should be kept in mind while using
+ * this class.

+ * \a zip is the pointer to the existing QuaZip object. This
+ * QuaZipFile object then can be used to read current file in the
+ * \a zip or to write to the file inside it.
+ *
+ * \warning Using this constructor for reading current file can be
+ * tricky. Let's take the following example:
+ * \code
+ * QuaZip zip("archive.zip");
+ * zip.open(QuaZip::mdUnzip);
+ * zip.setCurrentFile("file-in-archive");
+ * QuaZipFile file(&zip);
+ * file.open(QIODevice::ReadOnly);
+ * // ok, now we can read from the file
+ * file.read(somewhere, some);
+ * zip.setCurrentFile("another-file-in-archive"); // oops...
+ * QuaZipFile anotherFile(&zip);
+ * anotherFile.open(QIODevice::ReadOnly);
+ * anotherFile.read(somewhere, some); // this is still ok...
+ * file.read(somewhere, some); // and this is NOT
+ * \endcode
+ * So, what exactly happens here? When we change current file in the
+ * \c zip archive, \c file that references it becomes invalid
+ * (actually, as far as I understand ZIP/UNZIP sources, it becomes
+ * closed, but QuaZipFile has no means to detect it).
+ *
+ * Summary: do not close \c zip object or change its current file as
+ * long as QuaZipFile is open. Even better - use another constructors
+ * which create internal QuaZip instances, one per object, and
+ * therefore do not cause unnecessary trouble. This constructor may
+ * be useful, though, if you already have a QuaZip instance and do
+ * not want to access several files at once. Good example:
+ * \code
+ * QuaZip zip("archive.zip");
+ * zip.open(QuaZip::mdUnzip);
+ * // first, we need some information about archive itself
+ * QByteArray comment=zip.getComment();
+ * // and now we are going to access files inside it
+ * QuaZipFile file(&zip);
+ * for(bool more=zip.goToFirstFile(); more; more=zip.goToNextFile()) {
+ * file.open(QIODevice::ReadOnly);
+ * // do something cool with file here
+ * file.close(); // do not forget to close!
+ * }
+ * zip.close();

+ Copyright (C) 1998-2005 Gilles Vollant
+
+ This unzip package allow creates .ZIP file, compatible with PKZip 2.04g
+ WinZip, InfoZip tools and compatible.
+ Multi volume ZipFile (span) are not supported.
+ Encryption compatible with pkzip 2.04g only supported
+ Old compressions used by old PKZip 1.x are not supported
+
+ For uncompress .zip file, look at unzip.h
