Added zlib, quazip, basicxmlsyntaxhighlighter, conditionalsemaphore and linenumberdisplay libraries. zlib and quazip are pre-compiled, but you can compile them yourself, just delete the dll files (or equivalent binary files to your OS)

| 2 | Q. Is there any way to use \doxyref{QuaZipFile}{p.}{classQuaZipFile} in {\bf Qt} where you are supposed to use normal (non-\/zipped) file, but not through {\bf QIODevice} API?

| 4 | A. Usually not. For example, if you are passing file name to some database driver (like SQLite), {\bf Qt} usually just passes this name down to the 3rd-\/party library, which is usually does not know anything about {\bf QIODevice} and therefore there is no way to pass \doxyref{QuaZipFile}{p.}{classQuaZipFile} as normal file. However, if we are talking about some place where you pass file name, and then indirectly use {\bf QFile} to open it, then it is a good idea to make overloaded method, which accepts a {\bf QIODevice} pointer. Then you would be able to pass \doxyref{QuaZipFile}{p.}{classQuaZipFile} as well as many other nice things such as {\bf QBuffer} or {\bf QProcess}.

| 7 | Q. Can QuaZIP handle files larger than 4GB? What about zip64 standard?

| 9 | A. Starting with version 0.6, QuaZIP uses Minizip 1.1 with zip64 support which should handle large files perfectly. The zip64 support in Minizip looks like it's not 100\% conforming to the standard, but 3rd party tools seem to have no problem with the resulting archives.

| 12 | Q. Can QuaZIP write archives to a sequential {\bf QIODevice} like QTcpSocket?
|

| 14 | A. Not yet. It is not supported by vanilla Minizip (the back-\/end QuaZIP uses), although theoretically possible according to the ZIP standard. It would require some Minizip modifications that would allow it to detect non-\/seekable I/O and produce necessary output structures. QuaZIP already writes data descriptor which is necessary for non-\/seekable I/O. The only thing that is apparently left is to make Minizip fill local headers with correct values and forget about seeking after closing the file.
