Modules sal, salhelper, cppu, cppuhelper, codemaker (selectively) and odk have kept them, in order not to break external API (the automatic using declaration is LO-internal). Change-Id: I588fc9e0c45b914f824f91c0376980621d730f09
Helpers for using cppu in C++, e.g. templates for implementing UNO components, bootstrapping stuff. Get UNO up and running. See also: [http://wiki.services.openoffice.org/wiki/Uno/Cpp/Modules/CPPUhelper]
