-/** \page usage Usage
- * 
- * This page provides general information on QuaZIP usage. See classes
- * QuaZip and QuaZipFile for the detailed documentation on what can
- * QuaZIP do and what can not. Also, reading comments in the zip.h and
- * unzip.h files (taken from the original ZIP/UNZIP package) is always a
- * good idea too. After all, QuaZIP is just a wrapper with a few
- * convenience extensions and reimplementations.
- *
- * QuaZip is a class representing ZIP archive, QuaZipFile represents a
- * file inside archive and subclasses QIODevice as well.
- *
- * \section terminology Terminology
- *
- * "QuaZIP" means whole this library, while "QuaZip" (not case
- * difference) is just one class in it.
- *
- * "ZIP/UNZIP API" means the original API of the Gilles Vollant's
- * ZIP/UNZIP package. I did not alter it in any way to make it easier to
- * port to the future ZIP/UNZIP versions.
- *
- * "ZIP", "ZIP archive" or "ZIP file" means any ZIP archive. Typically
- * this is a plain file with ".zip" (or ".ZIP") file name suffix.
- *
- * "A file inside archive", "a file inside ZIP" or something like that
- * means file either being read or written from/to some ZIP archive.
- *
- * \section error-handling Error handling
- *
- * Almost any call to ZIP/UNZIP API return some error code. Most of the
- * original API's error checking could be done in this wrapper as well,
- * but it would cause unnecessary code bloating without any benefit. So,
- * QuaZIP only checks for situations that ZIP/UNZIP API can not check
- * for. For example, ZIP/UNZIP API has no "ZIP open mode" concept
- * because read and write modes are completely separated. On the other
- * hand, to avoid creating classes like "QuaZipReader", "QuaZipWriter"
- * or something like that, QuaZIP introduces "ZIP open mode" concept
- * instead, thus making it possible to use one class (QuaZip) for both
- * reading and writing. But this leads to additional open mode checks
- * which are not done in ZIP/UNZIP package.
- *
- * Therefore, error checking is two-level (QuaZIP's level and ZIP/UNZIP
- * API level), which sometimes can be confusing, so here are some
- * advices on how the error checking should be properly done:
- *
- * - Both QuaZip and QuaZipFile have getZipError() function, which return
- *   error code of the last ZIP/UNZIP API call. Most function calls
- *   reset error code to UNZ_OK on success and set error code on
- *   failure. Some functions do not reset error code. Most of them are
- *   \c const and do not access ZIP archive in any way. Some, on the
- *   other hand, \em do access ZIP archive, but do not reset or set
- *   error code. For example, QuaZipFile::pos() function. Such functions
- *   are explicitly marked in the documentation.
- * - Most functions have its own way to report errors, by returning a
- *   null string, negative value or \c false. If such a function returns
- *   error value, call getZipError() to get more information about
- *   error. See "zip.h" and "unzip.h" of the ZIP/UNZIP package for error
- *   codes.
- * - If the function returns error-stating value (like \c false), but
- *   getZipError() returns UNZ_OK, it means that you did something
- *   obviously wrong. For example, tried to write in the archive open
- *   for reading or not open at all. You better just do not do that!
- *   Most functions also issue a warning using qWarning() function in
- *   such cases. See documentation for a specific function for details
- *   on when it should not be called.
- *
- * I know that this is somewhat messy, but I could not find a better way
- * to do all the error handling.
