Added support for amalgated source and header generation (a la sqlite). Refer to README.txt section "Generating amalgated source and header" for detail.

The amalgated sources are generated by concatenating JsonCpp source in the correct order and defining macro JSON_IS_AMALGATED to prevent inclusion of other headers. Sources and header has been modified to prevent any inclusion when this macro is defined.

The script amalgate.py handle the generation.

(e.g. MSVC 2008 command prompt in start menu) before running scons.

* Generating amalgated source and header
======================================
JsonCpp is provided with a script to generate a single header and a single
source file to ease inclusion in an existing project.
The amalgated source can be generated at any time by running the following
command from the top-directory (requires python 2.6):
python amalgate.py
It is possible to specify header name. See -h options for detail. By default,
the following files are generated:
- dist/jsoncpp.cpp: source file that need to be added to your project
- dist/json/json.h: header file corresponding to use in your project. It is
equivalent to including json/json.h in non-amalgated source. This header
only depends on standard headers.
- dist/json/json-forwards.h: header the provides forward declaration
of all JsonCpp types. This typically what should be included in headers to
speed-up compilation.
The amalgated sources are generated by concatenating JsonCpp source in the
correct order and defining macro JSON_IS_AMALGATED to prevent inclusion of
other headers.
* Using json-cpp in your project:
===============================
include/ should be added to your compiler include path. jsoncpp headers should be included as follow:
