* \anchor faq-GPL Q. Is it possible to release an LGPL version of the
* QuaZip?
*
* A. I do not know much about licensing, so I can answer for sure, but
* QuaZip was developed using Open Source edition of Qt, so I see no
* way it could be released under anything except GPL.
*
* \anchor faq-non-QIODevice Q. Is there any way to use QuaZipFile in Qt
* where you are supposed to use normal (non-zipped) file, but not
* through QIODevice API?
*
* A. Usually not. For example, if you are passing file name to some
* database driver (like SQLite), Qt usually just passes this name down
* to the 3rd-party library, which is usually does not know anything
* about QIODevice and therefore there is no way to pass QuaZipFile as
* normal file. However, if we are talking about some place where you
* pass file name, and then indirectly use QFile to open it, then it is
* a good idea to make overloaded method, which accepts QIODevice
* pointer. Then you would be able to pass QuaZipFile as well as many
* other nice things such as QBuffer or QProcess.
