The internal libraries make use of external libraries. Information on the external libraries and on where to find them  CIT are available below:

• Documentation: list of the links to external libraries
• Libraries at CIT: /home/waveburst/SOFT: path to the external libraries and pakages at CIT

Two external libraries are necessary to run cWB: ROOT and FRAMELIB. The ROOT libraries, in particular, are used in two modes: the compiled mode, as a general library, and the interpreted mode, as an interpreter for C and C++ code. The cWB classes are accessible via the interpreter and can be used interactively via the root shell or as ROOT macros (tutorials. The pre and post-production commands are implemented as ROOT macros : pipeline macros
