core as a directory name is usually not a good idea

Let's follow the other places in qtbase where the
directory is named corelib.

-
-    Many C++ classes in Qt use implicit data sharing to maximize
-    resource usage and minimize copying. Implicitly shared classes are
-    both safe and efficient when passed as arguments, because only a
-    pointer to the data is passed around, and the data is copied only
-    if and when a function writes to it, i.e., \e {copy-on-write}.

-
-    \section1 Overview
-
-    A shared class consists of a pointer to a shared data block that
-    contains a reference count and the data.
-
-    When a shared object is created, it sets the reference count to 1. The
-    reference count is incremented whenever a new object references the
-    shared data, and decremented when the object dereferences the shared
-    data. The shared data is deleted when the reference count becomes
-    zero.
-
-    \keyword deep copy
-    \keyword shallow copy
-
-    When dealing with shared objects, there are two ways of copying an
-    object. We usually speak about \e deep and \e shallow copies. A deep
-    copy implies duplicating an object. A shallow copy is a reference
-    copy, i.e. just a pointer to a shared data block. Making a deep copy
-    can be expensive in terms of memory and CPU. Making a shallow copy is
-    very fast, because it only involves setting a pointer and incrementing
-    the reference count.
-
-    Object assignment (with operator=()) for implicitly shared objects is
-    implemented using shallow copies.
-
-    The benefit of sharing is that a program does not need to duplicate
-    data unnecessarily, which results in lower memory use and less copying
-    of data. Objects can easily be assigned, sent as function arguments,
-    and returned from functions.
-
-    Implicit sharing takes place behind the scenes; the programmer
-    does not need to worry about it. Even in multithreaded
-    applications, implicit sharing takes place, as explained in
-    \l{Thread-Support in Qt Modules#Threads and Implicitly Shared Classes}
-    {Threads and Implicitly Shared Classes}.
-
-    When implementing your own implicitly shared classes, use the
-    QSharedData and QSharedDataPointer classes.
-
-    \section1 Implicit Sharing in Detail
-
-    Implicit sharing automatically detaches the object from a shared
-    block if the object is about to change and the reference count is
-    greater than one. (This is often called \e {copy-on-write} or
-    \e {value semantics}.)
-
-    An implicitly shared class has total control of its internal data. In
-    any member functions that modify its data, it automatically detaches
-    before modifying the data.
-
-    The QPen class, which uses implicit sharing, detaches from the shared
-    data in all member functions that change the internal data.
-
-    Code fragment:
-    \snippet doc/src/snippets/code/doc_src_groups.cpp 0
-
-
-    \section1 List of Classes
-
-    The classes listed below automatically detach from common data if
-    an object is about to be changed. The programmer will not even
-    notice that the objects are shared. Thus you should treat
-    separate instances of them as separate objects. They will always
-    behave as separate objects but with the added benefit of sharing
-    data whenever possible. For this reason, you can pass instances
-    of these classes as arguments to functions by value without
-    concern for the copying overhead.
-
-    Example:
-    \snippet doc/src/snippets/code/doc_src_groups.cpp 1
-
-    In this example, \c p1 and \c p2 share data until QPainter::begin()
-    is called for \c p2, because painting a pixmap will modify it.
-
-    \warning Do not copy an implicitly shared container (QMap,
-    QVector, etc.) while you are iterating over it using an non-const
-    \l{STL-style iterator}.
