+QuaZIP is a simple C++ wrapper over Gilles Vollant's ZIP/UNZIP package
+that can be used to access ZIP archives. It uses the Qt toolkit.
+
+QuaZIP allows you to access files inside ZIP archives using QIODevice
+API, and - yes! - that means that you can also use QTextStream,
+QDataStream or whatever you would like to use on your zipped files.
+
+QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both
+reading from and writing to ZIP archives.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
