    \class QUrlInfo
    \brief The QUrlInfo class stores information about URLs.

    \ingroup io
    \ingroup network

    The information about a URL that can be retrieved includes name(),
    permissions(), owner(), group(), size(), lastModified(),
    lastRead(), isDir(), isFile(), isSymLink(), isWritable(),
    isReadable() and isExecutable().

    You can create your own QUrlInfo objects passing in all the
    relevant information in the constructor, and you can modify a
    QUrlInfo; for each getter mentioned above there is an equivalent
    setter. Note that setting values does not affect the underlying
    resource that the QUrlInfo provides information about; for example
    if you call setWritable(true) on a read-only resource the only
    thing changed is the QUrlInfo object, not the resource.

    \sa QUrl, {FTP Example}
*/

/*!
    \enum QUrlInfo::PermissionSpec

    This enum is used by the permissions() function to report the
    permissions of a file.

    \value ReadOwner The file is readable by the owner of the file.
    \value WriteOwner The file is writable by the owner of the file.
    \value ExeOwner The file is executable by the owner of the file.
    \value ReadGroup The file is readable by the group.
    \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.
