Dump cling::Value within setNoAlloc routines because this is its lifespan, otherwise gets deleted if nobody requested it. I.e it was created only for value printing purposes. Dump cling::Value outside setWithAlloc because the actual value is not put inside until the call to ::new finishes, thus we need to do it outside, i.e in EvaluateInternal. Switch on the ValueExtraction synthesizer even when 'just' value printing. We depend on it. Must be factored out properly in one class. Stop attaching the value printing template magic, which didn't work in some cases. Update the ref file, because now there is better type information. Adapt the user-defined printout functions (TDatime).

##INSTALLATION
###Binaries
We offer binary snapshots for download at https://ecsft.cern.ch/dist/cling
###Source
CLING source depends on the LLVM[1] and CLANG[2] headers and libraries.
You will also need CMake[3] >= 2.6.1 or GNU Make to build all of those
packages and subversion[4] and git[5] to get the source code.
[1] http://llvm.org
[2] http://clang.llvm.org
[3] http://cmake.org
[4] http://subversion.tigris.org
[5] http://git-scm.com
####Building
Building LLVM and CLANG you must:
- Check out the sources:
git clone http://root.cern.ch/git/llvm.git src
cd src
git checkout cling-patches
cd tools
git clone http://root.cern.ch/git/cling.git
git clone http://root.cern.ch/git/clang.git
cd clang
git checkout cling-patches
- Configure, build and install them, either using CMake:
cd ..
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/some/install/dir \
-DLLVM_TARGETS_TO_BUILD=CBackend\;CppBackend\;X86 \
-DCMAKE_BUILD_TYPE=Debug \
../src
make
make install
- or GNU Make (see ../src/configure --help for all options):
cd ..
mkdir build
cd build
../src/configure --prefix=/some/install/dir
make
make install
##USAGE
To get started run: /some/install/dir/bin/cling --help
or type
/some/install/dir/bin/cling
[cling]$ .help
##DEVELOPERS' CORNER:
We have doxygen documentation of cling's code at:
