+    \class QFileInfo
+    \reentrant
+    \brief The QFileInfo class provides system-independent file information.
+
+    \ingroup io
+
+    QFileInfo provides information about a file's name and position
+    (path) in the file system, its access rights and whether it is a
+    directory or symbolic link, etc. The file's size and last
+    modified/read times are also available.
+
+    A QFileInfo can point to a file with either a relative or an
+    absolute file path. Absolute file paths begin with the directory
+    separator "/" (or with a drive specification on Windows). Relative
+    file names begin with a directory name or a file name and specify
+    a path relative to the current working directory. An example of an
+    absolute path is the string "/tmp/quartz". A relative path might
+    look like "src/fatlib". You can use the function isRelative() to
+    check whether a QFileInfo is using a relative or an absolute file
+    path. You can call the function convertToAbs() to convert a
+    relative QFileInfo's path to an absolute path.
+
+    The file that the QFileInfo works on is set in the constructor or
+    later with setFile(). Use exists() to see if the file exists and
+    size() to get its size.
+
+    To speed up performance, QFileInfo caches information about the
+    file. Because files can be changed by other users or programs, or
+    even by other parts of the same program, there is a function that
+    refreshes the file information: refresh(). If you want to switch
+    off a QFileInfo's caching and force it to access the file system
+    every time you request information from it call setCaching(FALSE).
+
+    The file's type is obtained with isFile(), isDir() and
+    isSymLink(). The readLink() function provides the name of the file
+    the symlink points to.
+
+    Elements of the file's name can be extracted with dirPath() and
+    fileName(). The fileName()'s parts can be extracted with
+    baseName() and extension().
+
+    The file's dates are returned by created(), lastModified() and
+    lastRead(). Information about the file's access permissions is
+    obtained with isReadable(), isWritable() and isExecutable(). The
+    file's ownership is available from owner(), ownerId(), group() and
+    groupId(). You can examine a file's permissions and ownership in a
+    single statement using the permission() function.
+
+    If you need to read and traverse directories, see the QDir class.
+*/
+
+/*!
+    \enum QFileInfo::PermissionSpec
+
+    This enum is used by the permission() function to report the
+    permissions and ownership of a file. The values may be OR-ed
+    together to test multiple permissions and ownership values.
+
+    \value ReadUser The file is readable by the user.
+    \value WriteUser The file is writable by the user.

+    \value WriteGroup The file is writable by the group.
+    \value ExeGroup The file is executable by the group.
+    \value ReadOther The file is readable by anyone.
+    \value WriteOther The file is writable by anyone.
+    \value ExeOther The file is executable by anyone.
